Changes here are:
- Split out string format module sub-test to a separate test file, so it
can be skipped on targets that don't have str% capabilities.
- Print the whole type instead of `.__name__` to support targets that don't
have `.__name__` enabled (this still tests the same thing).
- Print `RuntimeError` exception message to be sure the correct exception
is being raised.
This test now runs on unix and zephyr minimal configurations.

Running the tests now requires CPython 3.8.2 or newer, which was
released February 2020 and should be widely available.
A few examples of features that were previously not supported by CPython,
but which are now:
- %-formatting for bytes and bytearray (PEP 461), CPython 3.5
- annotated variables (PEP 526), CPython 3.6
- assignment expressions (PEP 572), CPython 3.8
Note that `basics/fun_code_full.py.exp` is added here because that requires
CPython 3.10 or newer.

py: Add MICROPY_USE_GCC_MUL_OVERFLOW_INTRINSIC.
...
Most MCUs apart from Cortex-M0 with Thumb 1 have an instruction
for computing the "high part" of a multiplication (e.g., the upper
32 bits of a 32x32 multiply).
When they do, gcc uses this to implement a small and fast
overflow check using the __builtin_mul_overflow intrinsic, which
is preferable to the guard division method previously used in smallint.c.
However, in contrast to the previous mp_small_int_mul_overflow
routine, which checks that the result fits not only within mp_int_t
but is SMALL_INT_FITS(), __builtin_mul_overflow only checks for
overflow of the C type. As a result, a slight change in the code
flow is needed for MP_BINARY_OP_MULTIPLY.
Other sites using mp_small_int_mul_overflow already had the
result value flow through to a SMALL_INT_FITS check so they didn't
need any additional changes.
Do similarly for the _ll and _ull multiply overflows checks.

tools/mpremote: Workaround ESP DTR/RTS reset quirk at disconnect time.
...
The problem with ESP board spurious reset happens at disconnect time on
Windows (clearing DTR before RTS triggers a reset).
Previous workarounds tried to detect possible ESP boards and apply the
correct DTR and RTS settings when opening the port.
Instead, we can manually clear RTS before closing the port and thereby
avoid the reset issue. Opening the port can keep the default behaviour
(RTS & DTR both set).
close() is called from a finally block in the mpremote main module
(via do_disconnect()) - so this should always happen provided the Python
process isn't terminated by the OS.
One additional workaround is needed to prevent a spurious reset first time
a Silicon Labs CP210x-based ESP board is opened by mpremote after
enumeration.

py/runtime: Support importing a method from an instance.
...
This change follows CPython behaviour, allowing use of:
from instance import method
to import a bound method from a class instance, eg registered via
setting `sys.modules["instance"] = instance`.
Admittedly this is probably a very rarely used pattern in Python, but it
resolves a long standing comment about whether or not this is actually
possible (it turns out it is possible!). A test is added to show how it
works.
The main reason for this change is to fix a problem with imports in the
webassembly port: prior to this fix, it was not possible to do `from
js_module import function`, where `js_module` is a JavaScript object
registered to be visible to Python through the webassembly API function
`registerJsModule(js_module)`. But now with this fix that is possible.

It's frequently the case that a developer will want to compare the object
code size of various alternatives. When this can be done at the single
object code level, the turnaround is faster.
Provide a rule `$(BUILD)/%.sz` to print the size of a given object.
Because it is a normal Makefile target that depends on an object file, it
rebuilds the object file if needed.

webassembly: Improve identity and fix bug with lost JsProxy refs.
...
Commit ffa98cb014#17758 , a further optimisation is to make identity work in
that case, eg `js.Object is js.Object` should be true (on the Python side).
This commit implements that, by keeping track of all `JsProxy` Python
objects and reusing them where possible: where the underlying JS ref is
equal, ie they point to the same JS object. That reduces memory churn and
gives better identity behaviour of JS objects proxied over to Python.
As part of this, a bug is fixed where JS objects can be freed while there's
still a `JsProxy` referring to that JS object. A test is added for that
exact scenario, and the test now passes.

webassembly: Do GC in return path rather than entry path.
...
Doing GC calls in the entry path (when JavaScript calls into MicroPython at
the top/outer level) can lead to freeing of objects which are still in use.
This is because the (JavaScript) objects are referenced in the input
arguments to the C functions and they are not yet converted to full proxy
objects and not yet tracked properly by the live-object tracker.

nrf/modules/machine/spi: Print SPI baudrate, polarity and phase.

On most ports, printing an instance of machine.SPI gives something like:
>>> machine.SPI(1)
SPI(1, baudrate=328125, polarity=0, phase=0, bits=8)
This commit makes the nrf port do the same.
The reason for this change is:
- make nrf consistent with other ports
- allow the `tests/extmod/machine_spi_rate.py` to run on the nrf port (this
tests parses the output of str(spi) to get the actual baudrate)

py/stream: Reuse write implementation for readinto.
...
This commit refactors some common code in the core stream implementation,
to reduce code size while retaining the same functionality.
With the factoring, `readinto`/`readinto1` could now support an additional
4th argument (like write) but it's best not to introduce even more CPython
incompatibility, so they are left as having a maximum of 3 args.
