Reduces ESP32_GENERIC_C6 application flash size from 2024432 to
1813216 (206KB smaller).
Also has benefit of reducing D/IRAM size, increasing free memory at
runtime (167187 to 148584, -18603 bytes).
Most of this savings comes from building with -Os instead of -O2,
but about 10KB comes from using the SPI flash functions from the ROM.

This commit fixes a linking issue on certain Arm toolchains where
library code is compiled with exception support.
If a library with exception support is included in the MicroPython
build, the linker had no place to put the stack unwinding tables
necessary to perform exception handling at runtime. This change adds a
new section to the linkerscript (and therefore the final ELF file) where
that data can be placed into.

This commit lets board use a different floating point mode rather than
the usual soft-float that was the original default for all QEMU-based
boards.
The configuration options are the same available in the "stm32" port.
Boards can set "MICROPY_FLOAT_IMPL" to either "float", "double", or
"none" to indicate which floating point mode they want, and optionally
"SUPPORTS_HARDWARE_FP_SINGLE" or "SUPPORTS_HARDWARE_FP_DOUBLE" can be
set to 1 to further indicate the hardware capabilities of the hardware
floating point unit, if present.

When disconnecting from PPP the modem sends a confirmation. This message
is received, like all messages, through the poll() method. lwIP may then
immediately call our status callback with code PPPERR_USER to indicate
the connection was closed. Our callback then immediately proceeds to
free the PCB. Thus, during each new iteration of the loop in poll() we
must check if we haven't disconnected in the meantime to prevent calling
the pppos_input_tcpip with a PCB that is now NULL.

This is a pretty fundamental module, and even minimal ports like unix and
zephyr minimal have it enabled. So, enabled it by default at the lowest
feature level.
Most things in the `sys` module are configurable, and off by default, so it
shouldn't add too much to ports that don't already have it enabled (which
is just the minimal port).
Also note that `sys` is still disabled on the bare-arm port, to keep that
ultra minimal. It means we now have bare-arm without `sys` and the minimal
port with `sys`. That will allow different code size comparisons if/when
new `sys` features are added.

This commit unifies the configuration of MICROPY_PY_CRYPTOLIB,
MICROPY_PY_HASHLIB_MD5 and MICROPY_PY_HASHLIB_SHA1, so they are enabled by
default if MICROPY_PY_SSL is enabled. This matches the existing
configuration of most of the ports.
With this change, all ports remain the same except:
- reneses-ra now enables MICROPY_PY_CRYPTOLIB, MICROPY_PY_HASHLIB_MD5 and
MICROPY_PY_HASHLIB_SHA1.
- rp2 now enables MICROPY_PY_HASHLIB_MD5.

The specific problem seems to be that the runtime "Python stack frame"
function call is several times more expensive in stack usage when running
with UBSan on older GCC (observed on gcc 11.4 as used in CI, would get
'RuntimeError: maximum recursion depth exceeded' when running some tests
with UBSan enabled.)
Other stack usage (i.e. from pushing things on the stack in Python) stays
the same. Whatever causes the usage seems to be mostly gone in later GCC
versions.
Includes a refactor to apply the same stack size multipliers
for the default thread stack size same as the main stack size.
This goes in a new port-specific header as it depends on macros
in misc.h, so can't be in mpconfigport.h.
A side effect of this is that the default thread stack size is
now doubled on ARM, same as the main stack size.

If PPP is still connected, freeing the PCB will fail and thus instead we
should trigger a disconnect and wait for the lwIP callback to actually
free the PCB.
When PPP is not connected we should check if the freeing failed, warn
the user if so, and only mark the connection as inactive if not.
When all this happens during garbage collection the best case is that
the PPP connection is already dead, which means the callback will be
called immediately and cleanup will happen correctly. The worst case is
that the connection is still alive, thus we are unable to free the PCB
(lwIP won't let us) and it remains referenced in the netif_list, meaning
a use-after-free happens later when lwIP traverses that linked list.
This change does not fully prevent that, but it *does* improve how the
PPP.active(False) method on the ESP32 port behaves: It no longer
immediately tries to free (and fails), but instead triggers a disconnect
and lets the cleanup happen correctly through the status callback.

the PPP input function was accidentally changed to use the non-safe API.
