When detecting the target platform, also check if it has threading and
whether the GIL is enabled or not (using the new attribute
`sys.implementation._thread`). If threading is available, add the thread
tests to the set of tests to run (unless the set of tests is explicitly
given).
With this change, the unix port no longer needs to explicitly run the set
of thread tests, so that line has been removed from the Makefile.
This change will make sure thread tests are run with other testing
combinations. In particular, thread tests are now run:
- on the unix port with the native emitter
- on macOS builds
- on unix qemu, the architectures MIPS, ARM and RISCV-64

These will run on all ports which support them, but importantly
they'll also run on ports that don't support arbitrary precision
but do support 64-bit long ints.
Includes some test workarounds to account for things which will overflow
once "long long" big integers overflow (added in follow-up commit):
- uctypes_array_load_store test was failing already, now won't parse.
- all the ffi_int tests contain 64-bit unsigned values, that won't parse
as long long.

This commit implements a method to detect at runtime if inline assembler
support is enabled, and if so which platform it targets.
This allows clean test runs even on modified version of ARM-based ports
where inline assembler support is disabled, running inline assembler tests
on ports that have such feature not enabled by default and manually
enabled, and allows to always run the correct inlineasm tests for ports
that support more than one architecture (esp32, qemu, rp2).

Previously to this commit, running the test suite on a bare-metal board
required specifying the target (really platform) and device, eg:
$ ./run-tests.py --target pyboard --device /dev/ttyACM1
That's quite a lot to type, and you also need to know what the target
platform is, when a lot of the time you either don't care or it doesn't
matter.
This commit makes it easier to run the tests by replacing both of these
options with a single `--test-instance` (`-t` for short) option. That
option specifies the executable/port/device to test. Then the target
platform is automatically detected.
The `--test-instance` can be passed:
- "unix" (the default) to use the unix version of MicroPython
- "webassembly" to test the webassembly port
- anything else is considered a port/device to pass to Pyboard
There are also some shortcuts to specify a port/device, following
`mpremote`:
- a<n> is short for /dev/ttyACM<n>
- u<n> is short for /dev/ttyUSB<n>
- c<n> is short for COM<n>
For example:
$ ./run-tests.py -t a1
Note that the default test instance is "unix" and so this commit does not
change the standard way to run tests on the unix port, by just doing
`./run-tests.py`.
As part of this change, the platform (and it's native architecture if it
supports importing native .mpy files) is show at the start of the test run.

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`.

This implements (most of) the PEP-498 spec for f-strings and is based on
https://github.com/micropython/micropython/pull/4998 by @klardotsh.
It is implemented in the lexer as a syntax translation to `str.format`:
f"{a}" --> "{}".format(a)
It also supports:
f"{a=}" --> "a={}".format(a)
This is done by extracting the arguments into a temporary vstr buffer,
then after the string has been tokenized, the lexer input queue is saved
and the contents of the temporary vstr buffer are injected into the lexer
instead.
There are four main limitations:
- raw f-strings (`fr` or `rf` prefixes) are not supported and will raise
`SyntaxError: raw f-strings are not supported`.
- literal concatenation of f-strings with adjacent strings will fail
"{}" f"{a}" --> "{}{}".format(a) (str.format will incorrectly use
the braces from the non-f-string)
f"{a}" f"{a}" --> "{}".format(a) "{}".format(a) (cannot concatenate)
- PEP-498 requires the full parser to understand the interpolated
argument, however because this entirely runs in the lexer it cannot
resolve nested braces in expressions like
f"{'}'}"
- The !r, !s, and !a conversions are not supported.
Includes tests and cpydiffs.

Commit cb68a5741a broke automatic Python
feature detection when running tests, because some detection relied on a
crash of a feature script returning exactly b"CRASH".
This commit fixes this and improves the situation by testing for the lack
of a known pass result, rather than an exact failure result.

This is consistent with the other 'micro' modules and allows implementing
additional features in Python via e.g. micropython-lib's sys.
Note this is a breaking change (not backwards compatible) for ports which
do not enable weak links, as "import sys" must now be replaced with
"import usys".
This adds the Python files in the tests/ directory to be formatted with
./tools/codeformat.py. The basics/ subdirectory is excluded for now so we
aren't changing too much at once.
In a few places `# fmt: off`/`# fmt: on` was used where the code had
special formatting for readability or where the test was actually testing
the specific formatting.
This commit adds backward-word, backward-kill-word, forward-word,
forward-kill-word sequences for the REPL, with bindings to Alt+F, Alt+B,
Alt+D and Alt+Backspace respectively. It is disabled by default and can be
enabled via MICROPY_REPL_EMACS_WORDS_MOVE.
Further enabling MICROPY_REPL_EMACS_EXTRA_WORDS_MOVE adds extra bindings
for these new sequences: Ctrl+Right, Ctrl+Left and Ctrl+W.
The features are enabled on unix micropython-coverage and micropython-dev.
MICROPY_LONGINT_IMPL_LONGLONG doesn't have overflow detection, so just
parsing a large number won't give an error, we need to print it out
to check that the whole number was parsed.
If sets are not enabled, set literals lead to SyntaxError during parsing,
so it requires feature_check. Set tests are skipped based on set_*.py
pattern.
