ESP32-C3 is not Xtensa-based, so build settings are now tailored a bit
better following that fact. ESP-IDF 5.x already adds architecture-specific
modules by itself so there is no need to specify either the `xtensa` or the
`riscv` module in the build settings.

This is a code factoring to have the Python bindings in one location, and
all the ports use those same bindings. For all ports except the two listed
below there is no functional change.
The nrf port has UART.sendbreak() removed, but this method previously did
nothing.
The zephyr port has the following methods added:
- UART.init(): supports setting timeout and timeout_char.
- UART.deinit(): does nothing, just returns None.
- UART.flush(): raises OSError(EINVAL) because it's not implemented.
- UART.any() and UART.txdone(): raise NotImplementedError.

This factors the basic top-level I2S class code from the ports into
extmod/machine_i2s.c:
- I2S class definition and method table.
- The init and deinit method wrappers.
- The make_new code.
Further factoring will follow.

There are currently 7 ports that implement machine.WDT and a lot of code is
duplicated across these implementations. This commit factors the common
parts of all these implementations to a single location in
extmod/machine_wdt.c. This common code provides the top-level Python
bindings (class and method wrappers), and then each port implements the
back end specific to that port.
With this refactor the ports remain functionally the same except for:
- The esp8266 WDT constructor now takes keyword arguments, and accepts the
"timeout" argument but raises an exception if it's not the default value
(this port doesn't support changing the timeout).
- The mimxrt and samd ports now interpret the argument to WDT.timeout_ms()
as signed and if it's negative truncate it to the minimum timeout (rather
than it being unsigned and a negative value truncating to the maximum
timeout).

Some targets like the ESP32-S3 use the IDF Component Manager to provide
additional dependencies to the build. Make sure to include these extra
components when collecting properties used by MicroPython-specific build
steps, like qstr preprocessing.

This adds named-pins support to the esp32 port, following other ports.
Since the name of esp32 CPU pins is just GPIOx, where x is an integer, the
Pin.cpu dict is not supported and CPU pins are just retrieved via their
existing integer "name" (the cost of adding Pin.cpu is about 800 bytes,
mostly due to the additional qstrs).
What this commit supports is the Pin.board dict and constructing a pin by
names given by a board. These names are defined in a pins.csv file at the
board level. If no such file exists then Pin.board exists but is empty.
As part of this commit, pin and pin IRQ objects are optimised to reduce
their size in flash (by removing their gpio_num_t entry). The net change
in firmware size for this commit is about -132 bytes.

This commit updates the esp32 port to work exclusively with ESP-IDF v5.
IDF v5 is needed for some of the newer ESP32 SoCs to work, and it also
cleans up a lot of the inconsistencies between existing SoCs (eg S2, S3,
and C3).
Support for IDF v4 is dropped because it's a lot of effort to maintain both
versions at the same time.
The following components have been verified to work on the various SoCs:
ESP32 ESP32-S2 ESP32-S3 ESP32-C3
