Also shrinks the "prefer internal" threshold to 8KB, any allocation larger
than this will try PSRAM first.

Change the mbedTLS config to use regular malloc() as well, instead of
internal only.  The default is set to internal-only due to to potential
physical security issue of readout via PSRAM on the original ESP32.
However, as MicroPython runs from plaintext flash and all other context is
in the MP heap of PSRAM then it's hard to see how worsens physical security
for MP.

This commit:
- Finds a common set of board feature tags and maps existing features to
  that reduced set.
- Removes some less-useful board feature tags.
- Ensures all MCUs are specified correctly.
- Ensures all boards have a vendor (and fixes some vendor names).

This is to make the downloads page show a less intimidating set of filters.

This changes the ESP32 WDT implementation to use a custom handle so that it
becomes possible to reset the WDT from a thread.

By default esp_task_wdt_add subscribes the task_id of the current task.
That means that if we're running in a different task we are unable to reset
the WDT, which prevents feeding the WDT from a thread directly, or even
from a timer (which may randomly run in a different task when there's
multiple threads).

As an added bonus, the name we set makes the error clearly specify that it
was the user-specified WDT that reset the chip.

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 applies to all machine modules which have pins as arguments.  Since
machine_pin_get_id() calls pin_find(), these pin arguments may be at the
moment either integer objects or Pin objects.  That allows for instance to
write

    uart = UART(1, tx=Pin(4), rx=Pin(5))

instead of

    uart = UART(1, tx=4, rx=5)

which is consistent with other ports.  Since this handling is done at a
single place in the code, extending that scheme to accept strings for named
pins is easy.

The new machine_pin_find() function accepts a Pin object and a integer

The legacy driver was deprecated in IDF v5, and crashes when the ISR
handler is called.  Instead of fixing the legacy code, this commit reworks
the machine.Timer class to use the low-level HAL driver.

Tested on ESP32, ESP32S2, ESP32S3 and ESP32C3.  Behaviour is the same as it
was before this commit, except the way the Timer object is printed, it now
gives more useful information (timer id, mode, period in ms).

This is a fix for commit bccbaa92:
- Should only wait for WIFI_EVENT_STA_START when invoked on the STA_IF
  interface.
- The WIFI_EVENT_STA_START event is generated every time the STA_IF
  interface is set active(True) and it was previously inactive, ie. not
  only after calling esp_wifi_start().
- Also wait for WIFI_EVENT_STA_STOP when deactivating the interface.
- Also wait for relevant AP events.

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:
