5bafb0bf68 tests: Convert all machine.UART tests to use target_wiring.
All the existing `machine.UART` tests in extmod and extmod_hardware are
converted to use the new `target_wiring` scheme, which removes a lot of
duplicated board-specific settings.

All the existing boards that were supported by these UART tests now have
their own `target_wiring` file.  Some configurations are board specific (eg
NUCLEO_WB55) and others are port specific.

907c5e9976 tests/extmod_hardware: Add basic tests for machine.Counter and Encoder.
These don't test any advanced features, just the basics.

This work was funded through GitHub Sponsors.

6558d519a2 tests/extmod_hardware: Add self unittest for I2CTarget.
This test uses a SoftI2C controller wired to an I2CTarget on the one board,
and tests all functionality of the I2CTarget class.

1ab1f857b3 tests/extmod_hardware/machine_uart_irq_break.py: Remove send_uart.
This is no longer needed, the esp32 port can now pass this test using just
a single UART.

29b5c2207c tests/extmod_hardware/machine_uart_irq_rxidle.py: Test multiple writes.
This tests that the RXIDLE callback is called correctly after a second lot

a4a098ff82 tests/extmod_hardware/machine_uart_irq_rxidle.py: Ignore inital IRQ.
On stm32, the hardware generates an RXIDLE IRQ after enabling the UART,
because the RX line is technically idle.

This adds a hardware test for `machine.PWM`.  It requires a jumper wire
between two pins, uses `machine.PWM` to output on one of them, and
`machine.time_pulse_us()` to time the PWM on the other pin (some boards
test more than one pair of pins).

It times both the high and low duty cycle (and hence the frequency) for a
range of PWM frequencies and duty cycles (including full on and full off).

Currently supported on:
- esp32 (needs a minor hack for initialisation, and some tests still fail)
- esp8266 (passes for frequencies 1kHz and less)
- mimxrt / Teensy 4.0 (passes)
- rp2 (passes)
- samd21 (passes for frequencies 2kHz and less)

These all require hardware connections, so live in a different directory.

Except for the IRQ_BREAK test of ESP32 devices a single UART with loopback
is sufficient.

General:
    SAMD21: Due to the limited flash size only SAMD21 devices with external
    flash support uart.irq().

IRQ_BREAK:
    ESP32 needs different UART devices for creating and sensing a break.
    Lacking a second UART the test is skipped for ESP32S2 and ESP32C3.  RP2
    does not pass the test reliable at 115200 baud, reason to be found.
    Thus the upper limit is set to 57600 Baud.

    Coverage:
        esp32  pass when different UART devices are used.
        rp2    pass up to 57600 baud

IRQ_RX:
    SAMD21: Being a slow device it needs data to be sent byte-by-byte at
    9600 baud, since the IRQ callback is scheduled delayed and then the
    flags do not match any more.  The data matches since it is queued in
    the FIFO resp. ringbuffer.

    CC3200: The test cannot be performed since no calls are accepted in the
    IRQ handler like u.read(). Skipped.

    Coverage:
        cc3200 fail due to major differences in the implementation.
        esp32  pass
        nrf    pass
        renesas-ra pass
        samd   pass see the notes.
        stm32  pass

IRQ_RXIDLE:
    STM32: With PyBoard the IRQ is called several times, but only once with
    the flag IRQ_RXIDLE set.

    Coverage:
        esp32    pass
        mimxrt   pass
        renesas-ra pass
        rp2      pass
        samd     pass for both SAMD21 and SAMD51
        stm32    fail. see notes.
