Now that some ports support multiple architectures (eg esp32 has both
Xtensa and RISC-V CPUs) it's no longer possible to set mpy-cross flags
based on the target, eg `./run-tests.py --target esp32`. Instead this
commit makes it so the `-march=xxx` argument to mpy-cross is detected
automatically via evaluation of `sys.implementation._mpy`.

Currently, the qemu-arm (and qemu-riscv) port has two build modes:
- a simple test that executes a Python string; and
- a full test that uses tinytest to embed all tests within the firmware,
then executes that and captures the output.
This is very different to all the other ports. A difficulty with using
tinytest is that with the large number of tests the firmware overflows its
virtual flash size. It's also hard to run tests via .mpy files and with
the native emitter. Being different to the other ports also means an extra
burden on maintenance.
This commit reworks the qemu-arm port so that it has a single build target
that creates a standard firmware which has a REPL. When run under
qemu-system-arm, the REPL acts like any other bare-metal port, complete
with soft reset (use machine.reset() to turn it off and exit
qemu-system-arm).
This approach gives many benefits:
- allows playing with a REPL without hardware;
- allows running the test suite as it would on a bare-metal board, by
making qemu-system-arm redirect the UART serial of the virtual device to
a /dev/pts/xx file, and then running run-tests.py against that serial
device;
- skipping tests is now done via the logic in `run-tests.py` and no longer
needs multiple places to define which tests to skip
(`tools/tinytest-codegen.py`, `ports/qemu-arm/tests_profile.txt` and also
`tests/run-tests.py`);
- allows testing/using mpremote with the qemu-arm port.
Eventually the qemu-riscv port would have a similar change.
Prior to this commit the test results were:
743 tests ok. (121 skipped)
With this commit the test results are:
753 tests performed (22673 individual testcases)
753 tests passed
138 tests skipped
More tests are skipped because more are included in the run. But overall
more tests pass.

Install the mingw variant of Python since it behaves more like a 'real'
Windows CPython than the msys2 variant: os.name == 'nt', not 'posix'. Note
that os.sep is still '/' though so we don't actually need to skip the
import_file test. This way one single Python version can be used both for
running run-tests.py and getting the expected test output.

The code generating the entry to the finally handler of an async-with
statement was simply wrong for the case of the native emitter. Among other
things the layout of the stack was incorrect.
This is fixed by this commit. The setup of the async-with finally handler
is now put in a dedicated emit function, for both the bytecode and native
emitters to implement in their own way (the bytecode emitter is unchanged,
just factored to a function).
With this fix all of the async-with tests now work when using the native
emitter.

This adds a QEMU-based bare metal RISC-V 32 bits port. For the time being
only QEMU's "virt" 32 bits board is supported, using the ilp32 ABI and the
RV32IMC architecture.

This commit adds a significant portion of the existing MicroPython asyncio
module to the webassembly port, using parts of the existing asyncio code
and some custom JavaScript parts.
The key difference to the standard asyncio is that this version uses the
JavaScript runtime to do the actual scheduling and waiting on events, eg
Promise fulfillment, timeouts, fetching URLs.
This implementation does not include asyncio.run(). Instead one just uses
asyncio.create_task(..) to start tasks and then returns to the JavaScript.
Then JavaScript will run the tasks.
The implementation here tries to reuse as much existing asyncio code as
possible, and gets all the semantics correct for things like cancellation
and asyncio.wait_for. An alternative approach would reimplement Task,
Event, etc using JavaScript Promise's. That approach is very difficult to
get right when trying to implement cancellation (because it's not possible
to cancel a JavaScript Promise).

Compare the full absolute path instead of relying on the path form
passed by the user.
For instance, this will make
python3 run-tests.py -d basics
python3 run-tests.py -d ./basics
python3 run-tests.py -d ../tests/basics
python3 run-tests.py -d /full/path/to/basics
all behave the same by correctly treating the bytes_compare3 and
builtin_help tests as special, whereas previously only the first
invocation would do that and hence result in these tests to fail
when called with a different path form.

The aim of this commit is to make it so that the existing thread tests can
be used to test the _thread module on the rp2 port. The rp2 port only
allows up to one thread to be created at a time, and does not have the GIL
enabled.
The following changes have been made:
- run-tests.py skips mutation tests on rp2, because there's no GIL.
- run-tests.py skips other tests on rp2 that require more than one thread.
- The tests stop trying to start a new thread after there is an OSError,
which indicates that the system cannot create more threads.
- Some of these tests also now run the test function on the main thread,
not just the spawned threads.
- In some tests the output printing is adjusted so it's the same regardless
of how many threads were spawned.
- Some time.sleep(1) are replaced with time.sleep(0) to make the tests run
a little faster (finish sooner when the work is done).
For the most part the tests are unchanged for existing platforms like esp32
and unix.

Previously when using --via-mpy, the file was compiled to tests/<tmp>.mpy
and then run using `micropython -m <tmp>` in the current cwd
(usually tests/). This meant that an import in the test would be resolved
relative to tests/.
This is different to regular (non-via-mpy) tests, where we run (for
example) `micropython basics/test.py` which means that an import would be
resolved relative to basics/.
Now --via-mpy matches the .py behavior. This is important because:
a) It makes it so import tests do the right thing.
b) There are directory names in tests/ that match built-in module names.
Furthermore, it always ensures the cwd (for both micropython and cpython)
is the test directory (e.g. basics/) rather than being left unset. This
also makes it clearer inside the test that e.g. file access is relative to
the Python file.
Updated tests with file paths to match.

During the initial handshake or subsequent renegotiation, the protocol
might need to read in order to write (or conversely to write in order
to read). It might be blocked from doing so by the state of the
underlying socket (i.e. there is no data to read, or there is no space
to write).
The library indicates this condition by returning one of the errors
`MBEDTLS_ERR_SSL_WANT_READ` or `MBEDTLS_ERR_SSL_WANT_WRITE`. When that
happens, we need to enforce that the next poll operation only considers
the direction that the library indicated.
In addition, mbedtls does its own read buffering that we need to take
into account while polling, and we need to save the last error between
read()/write() and ioctl().
This will make mpy-cross auto-detect. Allow overriding for non-default
configurations (e.g. using 32-bit build of the unix port).
Also use armv7m by default for qemu-arm (the default qemu target is
Cortex-M3).

Binaries built using the Make build system now no longer appear in the
working directory of the build, but rather in the build directory. Thus
some paths had to be adjusted.
Formerly, py/formatfloat would print whole numbers inaccurately with
nonzero digits beyond the decimal place. This resulted from its strategy
of successive scaling of the argument by 0.1 which cannot be exactly
represented in floating point. The change in this commit avoids scaling
until the value is smaller than 1, so all whole numbers print with zero
fractional part.
Fixes issue #4212.

This enables the new `-X realtime` runtime option when running tests on
