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.

An SSL stream can only handle CLOSE and POLL ioctls.  Other ones do not
make sense, or at least it doesn't make sense to pass the ioctl request
directly down to the underlying stream.

In particular MP_STREAM_GET_FILENO should not be passed to the underlying
stream because the SSL stream is not directly related to a file descriptor,
and the SSL stream must handle the polling itself.

The signature of this method was poller.poll(timeout=-1, flags=0, /) but
the flags argument was not documented and is not CPython compatible.  So
it's removed in this commit.

(The optional flags remains for the ipoll() method, which is documented.)

A previous commit removed the unix-specific select module implementation
and made unix use the common one.

This commit adds an optimisation so that the system poll function is used
when polling objects that have a file descriptor.  With this optimisation
enabled, if code registers both file-descriptor-based objects, and non-
file-descriptor-based objects with select.poll() then the following occurs:

- the system poll is called for all file-descriptor-based objects with a
  timeout of 1ms

- then the bare-metal polling implementation is used for remaining objects,
  which calls into their ioctl method (which can be in C or Python)

In the case where all objects have file descriptors, the system poll is
called with the full timeout requested by the caller.  That makes it as
efficient as possible in the case everything has a file descriptor.

Benefits of this approach:

- all ports use the same select module implementation

- the unix port now supports polling of all objects and matches bare metal
  implementations

- it's still efficient for existing cases where only files and sockets are
  polled (on unix)

- the bare metal implementation does not change

- polling of SSL objects will now work on unix by calling in to the ioctl
  method on SSL objects (this is required for asyncio ssl support)

Note that extmod/vfs_posix_file.c has poll disable when the optimisation is
enabled, because the code is not reachable when the optimisation is used.

To make it easier to extend and modify this polling implementation.
Signed-off-by: NDamien George <damien@micropython.org>

The unix port has a custom select module which only works with objects that
have a file descriptor, eg files and sockets.  On the other hand, bare
metal ports use the common extmod/modselect.c implementation of the select
module that supports polling of arbitrary objects, as long as those objects
provide a MP_STREAM_POLL in their ioctl implementation (which can be done
in C or Python).

This commit removes the unix-specific code and makes unix use the common
one provided by extmod/modselect.c instead.  All objects with file
descriptors implement MP_STREAM_POLL so they continue to work.

In applications that use little memory and run GC regularly, the cost of
the sweep phase quickly becomes prohibitives as the amount of RAM
increases.

On an ESP32-S3 with 2 MB of external SPIRAM, for example, a trivial GC
cycle takes a minimum of 40ms, virtually all of it in the sweep phase.

Similarly, on the UNIX port with 1 GB of heap, a trivial GC takes 47 ms,
again virtually all of it in the sweep phase.

This commit speeds up the sweep phase in the case most of the heap is empty
by keeping track of the ID of the highest block we allocated in an area
since the last GC.

The performance benchmark run on PYBV10 shows between +0 and +2%
improvement across the existing performance tests.  These tests don't
really stress the GC, so they were also run with gc.threshold(30000) and
gc.threshold(10000).  For the 30000 case, performance improved by up to
+10% with this commit.  For the 10000 case, performance improved by at
least +10% on 6 tests, and up to +25%.

Currently everything is available at the download page except

Previously this was explicitly enabled on esp32/stm32/renesas/mimxrt/samd,
but didn't get a default feature level because it wasn't in py/mpconfig.h.

With this commit it's now enabled at the "extra features" level, which adds
rp2, unix-standard, windows, esp8266, webassembly, and some nrf boards.

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.

When MICROPY_SCHEDULER_STATIC_NODES is enabled, the logic is unchanged.

When MICROPY_SCHEDULER_STATIC_NODES is disable, sched_state is now always
initialised to MP_SCHED_IDLE when calling mp_init().  For example, the use
of mp_sched_vm_abort(), if it aborts a running scheduled function, can lead
to the scheduler starting off in a locked state when the runtime is
restarted, and then it stays locked.  This commit fixes that case by
resetting sched_state.
