This commit adds the currently supported architecture flags value as the
upper part of "sys.implementation._mpy".
This had the side effect of perturbing quite a bit of testing
infrastructure and invalidating documentation related to MPY files. To
make the test suite run successfully and keep the documentation in sync
the following changes have been made:
* The target info feature check file now isolates eventual architecture
flags and adds them as a separate field
* The test runner now picks up the new architecture flags field, reports
it to STDOUT if needed and stores it for future uses
* Relevant test files for MPY files import code had to be updated to
mask out the architecture flags bits in order to perform correctly
* MPY file format documentation was updated to show how to mask off and
properly display the architecture flags information.
This works out of the box if the flag bits can fit in a smallint value
once merged with the MPY file header value.

MPY files can now hold data to be run on RV64IMC. This can be
accomplished by passing the `-march=rv64imc` flag to mpy-cross.

The unicode tests are now run on all targets that enable unicode. And
other unicode tests (namely `extmod/json_loads.py`) are now properly
skipped if the target doesn't have unicode support.

This simplifies the code by removing the explicit addition of the "float/"
test directory for certain targets. It also means the tests won't be added
incorrectly, eg on a unix build without float.

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

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`.
