3c9546ea09 esp32/mpconfigport: Disable I2CTarget on ESP32-C6 to reduce code size.
I2CTarget costs about 8k of flash size on ESP32-S2, and about 11k on
ESP32-C6.  The ESP32-C6 only has about 8k remaining, so disable I2CTarget
on that SoC until more flash can be made available.

327655905e esp32/modules/machine.py: Add Counter and Encoder classes.
Adds a Python override of the `machine` module, which delegates to the
built-in module and adds an implementation of `Counter` and `Encoder`,
based on the `esp32.PCNT` class.

c3f3339c87 esp32/modesp32: Add esp32.PCNT class.
Add a new `esp32.PCNT` class that provides complete, low-level support to
the ESP32 PCNT pulse counting hardware units.

This can be used as a building block to implement the higher-level
`machine.Counter` and `machine.Encoder` classes.

This is enabled by default on all OG, S2, S3, C6 boards, but not on C3 (as
the PCNT peripheral is not supported).

The functionality is similar to the RP2 implementation.  The supported
address size is 7 bit.  In order to achieve a sufficient response, the
target I2C IRQ handler has to run from RAM, causing much more code moved to

dbbaa959c8 py/formatfloat: Improve accuracy of float formatting code.
Following discussions in PR #16666, this commit updates the float
formatting code to improve the `repr` reversibility, i.e. the percentage of
valid floating point numbers that do parse back to the same number when
formatted by `repr` (in CPython it's 100%).

This new code offers a choice of 3 float conversion methods, depending on
the desired tradeoff between code size and conversion precision:

- BASIC method is the smallest code footprint

- APPROX method uses an iterative method to approximate the exact
  representation, which is a bit slower but but does not have a big impact
  on code size.  It provides `repr` reversibility on >99.8% of the cases in
  double precision, and on >98.5% in single precision (except with REPR_C,
  where reversibility is 100% as the last two bits are not taken into
  account).

- EXACT method uses higher-precision floats during conversion, which
  provides perfect results but has a higher impact on code size.  It is
  faster than APPROX method, and faster than the CPython equivalent
  implementation.  It is however not available on all compilers when using
  FLOAT_IMPL_DOUBLE.

Here is the table comparing the impact of the three conversion methods on
code footprint on PYBV10 (using single-precision floats) and reversibility
rate for both single-precision and double-precision floats.  The table
includes current situation as a baseline for the comparison:

              PYBV10  REPR_C   FLOAT  DOUBLE
    current = 364688   12.9%   27.6%   37.9%
    basic   = 364812   85.6%   60.5%   85.7%
    approx  = 365080  100.0%   98.5%   99.8%
    exact   = 366408  100.0%  100.0%  100.0%

ffa98cb014 webassembly/proxy_js: Reuse JsProxy ref if object matches.
This reduces memory use by reusing objects, and improves identity/equality
relationships of JavaScript objects on the Python side.

In 77bd8fe5b8 PyProxy's were reused when the
same Python object was proxied across to JavaScript.  This commit does the
same thing but for JsProxy's going from JS to Python.  If an existing
JsProxy reference exists for the JS object about to be proxied across, then
it's reused.

This helps reduce the number of alive objects (memory use), and, more
importantly, improves equality relationships of JavaScript objects on the
Python side.  Eg we now get, on the Python side:

    import js

    print(js.Object == js.Object)

that prints True.  Previously it was False.

Note that this change does not make identity work with `is`, for example
`js.Object is js.Object` is actually False.  With more work that could be
made True but for now we leave that as-is.

The behaviour with this commit matches Pyodide semantics.

4360da1684 zephyr/mpconfigport: Use MICROPY_CONFIG_ROM_LEVEL_BASIC_FEATURES.
This commit adjusts the configuration of the standard zephyr build to use
MICROPY_CONFIG_ROM_LEVEL_BASIC_FEATURES.  That's a lot cleaner than
explicitly enabling/disabling options, and allows boards to more easily
fine-tune the settings, eg select a different feature level.

Features that are now enabled are:
- async/await keyword support
- `filter`, `property` and `reversed` builtins
- `range` attributes
- `str.count()` method
- `array` module with `array.array` object
- `collections` module with `collections.namedtuple` object
- `struct` module with everything
- `id = const()` and constant folding in the compiler

Bulding qemu_cortex_m3, the code size was originally:

    Memory region         Used Size  Region Size  %age Used
               FLASH:      193864 B       256 KB     73.95%
                 RAM:       61992 B        64 KB     94.59%

and with this commit it is now:

    Memory region         Used Size  Region Size  %age Used
               FLASH:      200698 B       256 KB     76.56%
                 RAM:       61992 B        64 KB     94.59%

That's a mild increase of +6834 bytes flash usage for a good selection of
new features.

68434b4be7 zephyr/mpconfigport_minimal: Use MICROPY_CONFIG_ROM_LEVEL_MINIMUM.
This commit adjusts the configuration of the minimal zephyr build to use
MICROPY_CONFIG_ROM_LEVEL_MINIMUM.  That's a lot cleaner than explicitly
enabling/disabling options.

Prior to this change the minimal build for qemu_cortex_m3 had size:

    Memory region         Used Size  Region Size  %age Used
               FLASH:      114436 B       256 KB     43.65%
                 RAM:       26320 B        64 KB     40.16%

and had the following test results (running using the CI settings, ie
`-d basics float --exclude inf_nan_arith`):

    352 tests performed (7092 individual testcases)
    352 tests passed
    254 tests skipped: ...

With the changes here the qemu_cortex_m3 size is now:

    Memory region         Used Size  Region Size  %age Used
               FLASH:       99428 B       256 KB     37.93%
                 RAM:       26312 B        64 KB     40.15%

That's a good decrease of about 15k firmware size.  And the test suite
still passes with:

    342 tests performed (6776 individual testcases)
    341 tests passed
    265 tests skipped: ...

77c9eb7795 esp32: Add "Free RAM" optimisation config flags.
This is necessary for ESP32-C2 Wi-Fi & BT to work reliably (and for TLS to
work at all). On IDF 5.4.2 the free static RAM goes from 60KB to 100KB, and
there will also be a reduction in lwIP & Wi-Fi memory use at runtime.

The performance trade-off seems low for most use cases, although it will
probably be significant for certain combinations of load (i.e. heavy
TCP/IP, heavy BT throughput, and some peripheral driver functions).

Added as a set of config flags because this is potentially useful on other
SoCs where the goal is to maximise RAM available for MicroPython.
