The `rp2` package use a global dict `_pio_funcs` to populate a namespace
for `@asm_pio` functions to be executed in. That dict is not cleaned up
after use, keeping references to bound methods of a `PIOASMEmit`. By not
setting/clearing all the functions, `asm_pio_encode` unintentionally allows
the use of the old directives (harmless) as well as `jmp` (in general,
produces the wrong output).
Fix that by making sure `_pio_funcs` is returned to its original state
after using it:
- For `@asm_pio` update the target dict from `_pio_funcs` and then set
additional functions as needed, leaving `_pio_funcs` unchanged.
- For `asm_pio_encode`, borrow `_pio_funcs` to use as globals (avoiding a
bunch of memory alloc/free) but delete the instruction entries after use.

Add support for `mpremote mip install package.json` where `package.json` is
a json file on the local filesystem.
Without this, package json files can only be loaded from http, https,
github or gitlab URLs.
This is useful for testing `package.json` files for pacages in development
and for constructing one's own `package.json` files for Python packages
which are not yet available for installation using mip.

The flash clock frequency may have been set to a different value by a
bootloader. Set the frequency according to the configured value. Use a
table of pre-calculated dividers to get the closest value for the flash
frequency, achieving for MIMXRT10xx:
30 -> 30.85 MHz
50 -> 49.65 MHz
60 -> 60 MHz
75 -> 75.13 MHz
80 -> 80 MHz
100 -> 99.31 Mhz
133 -> 132.92 MHz
166 -> 166.15 MHz
for MIMXRT1176:
30 -> 31 MHz
50 -> 52.8 MJz
60 -> 58.7 MHz
75 -> 75.4 MHz
80 -> 75.4 MHz
100 -> 105.6 MHz
133 -> 132 MHz
166 -> 176 MHz

And use these to initialize the LUT table properly for the various flash

easier to just keep one copy of the qspiflash_config structure with the LUT
table and update it during flash initialisation as needed.

Allowing to use e.g. the Adafruit bootloaders with MicroPython. The .uf2
file is created in addition to the .bin and .hex files allowing to use the
latter ones without the bootloader for debugging and testing.
Changes:
- Set the location of the ISR Vector and .text segment to 0x6000C000 and
0x6000C400.
- Reserve an area at the start of ITCM for a copy of the interrupt vector
table and copy the table on reset to this place.
- Extend `machine.bootloader()` by setting the magic number to enable the
bootloader on reset.
- Create a .uf2 file which skips the segments below 0x6000C000.
The bootloader has to be installed as a preparation step using the board
specific methods, but then the firmware's .uf2 file version can be
installed using the bootloader. The bootloader can be invoked with:
- double reset
- calling machine.bootloader()
- Using the touch1200 method
Double reset is hard to achieve on MIMXRT boards, since there is no clean
reset pin. Some MIMXRT boards provide it by switching the power.
Some boards are excluded from the .uf2 build:
- MIMXRT1050_EVK: The uf2 bootloader is built for the QSPI version of the
board. MicroPython supports the Hyperflash version.
- MIMXRT1176_EVK: No support for this board yet, but it should be possible.

This commit fixes the command used to run natmod tests, as it relied on
a string interpolation feature of the POSIX shell that was not working
as expected inside a makefile.
The interpolation was not performed from inside the makefile and the raw
command string was sent to the operating system for execution. Now the
command is run by using a different type of string substitution, which
explicitly performs the interpolation using a POSIX shell for-loop.

This commit lets the natmod tests runner to automatically detect the
architecture of the test target. This allows to avoid to explicitly
pass the architecture name to the runner in test scripts.
However, the ability to manually specify a target was not removed but it
was made optional. This way the user is able to override the
architecture name if needed (like if one wants to test an armv6 MPY on
an armv7 board).

When a port automatically compiles `mpy-cross`, if `USER_C_MODULES` is
provided by the user on the command line then it is also applied to the
`mpy-cross` build. That can lead to build errors if the path is relative
and not found when building `mpy-cross`.
Fix that by explicitly resetting `USER_C_MODULES` when invoking the
`mpy-cross` build.

Do this by tracking being inside gc collection with a
separate flag, GC_COLLECT_FLAG. In gc_free(),
ignore this flag when determining if the heap is locked.
* For finalisers calling gc_free() when heap is otherwise unlocked,
this allows memory to be immediately freed (potentially
avoiding a MemoryError).
* Hard IRQs still can't call gc_free(), as heap will be locked via
gc_lock().
* If finalisers are disabled then all of this code can be compiled
out to save some code size.

Currently a finalizer may run and access memory which has already been
freed. (This happens mostly during gc_sweep_all() but could happen during
any garbage collection pass.)
Includes some speed improvement tweaks to skip empty FTB blocks. These help
compensate for the inherent slowdown of having to walk the heap twice.

On mbedTLS ports with non-baremetal configs (mostly esp32, technically also
unix port), mbedTLS memory is allocated from the libc heap. This means an
old SSL socket may be holding large SSL buffers and preventing a new SSL
socket from being allocated.
As a workaround, trigger a GC pass and retry before failing outright.
This was originally implemented as a global mbedTLS calloc function, but
there is complexity around the possibility of C user modules calling into
mbedTLS without holding the GIL. It would be interesting to try making a
generic version for any malloc which fails, but this would require checking
for a Python thread and probably making the GIL recursive.
