Following the unix port.

Support for building variants with msvc was done by @stinos.

The application isn't necessarily called 'micropython' especially
not When using variants, i.e. the tests need to be ran using $(PROG).

This is the same fix as applied in uselect_poll_basic.py.

This makes sure changes from previous related commits actually work.

Via the MICROPY_HW_FLASH_DQS flag.

And how they relate to MicroPython.  As these features are implemented (or
the decision is made to not implement them) the tables can be updated to
document the differences between MicroPython and standard Python.

The qstr_last_chunk is not collected by the garbage collector.  This relies
on the assertion that qstr_pool_t also references the qstr_last_chunk.  If
an exception is raised while allocating the qstr_pool_t, qstr_last_chunk
has to be invalidated not to become a dangling reference at the next
garbage collection.

- Cleanup pyexec flags definitions so it's clear they are different.
- Use mp_uint_t for exec_flags because it should be unsigned.

  (espressif/esp-idf#8121).

After changing the bitstream implementation to use the RMT driver in
commit 72d8615
("esp32/machine_bitstream.c: Replace with RMT-based driver."), using
multiple `Neopixel` instances shows signal duplication between the
instances (i.e. a `write()` on one instance is written to all instances).

On invocation, the rmt driver configures the GPIO matrix to route the
output signal to the respective GPIO pin.  When called for a different
`NeoPixel` instance using a different pin, the new route is established,
but the old route still exists.  Now, the RMT output signal is sent to both
pins.

Fix this by setting the standard GPIO output function for the current pin
after uninstalling the RMT driver.

As a prerequisite to upgrading to Zephyr v2.7.0, upgrade CI to use
Zephyr docker image v0.21.0. In particular, this is needed to pick up a
newer CMake version because Zephyr v2.7.0 increased the minimum CMake
version required to 3.20.0.

The method was changed, but not for the CSx pins.  No functional change.

OCOTP_Init() has been removed from mphalport.c.  The library files are
missing for the MIMXRT1015, and for just reading the OCOTP the Init is not
required.

Sometimes frames could not be sent immediately because the controller was
still busy with previous frames.  Then, an error was returned to lwip.
This fix adds a limited number of retries for this busy state, waiting
100µs before the next attempt.  Typically the transmit succeeds now at the
second attempt.

Second change: Reset the controller for a clean state after soft reset.

Teensy 4.1 used different pins for SPI1 than Teensy 4.0, which made the
boards unnecessarily different.

If the board directory contains a manifest.py file, it will be included.
File not found errors will be ignored.

That caused Ethernet to lock up at high data rates after ~200MByte data
average in a row.  Tested now with data bursts up to 10 GByte and overall
data rates of ~8MByte/s at the Eth100 port.

Ensure the symmetry of PWM: the duty rate of X and Q channels was not 50%,
when it should have been.  That is evident at high frequencies, like 15Mhz
or 37.5 MHz.  At low frequencies the deviation mattered less.  The A/B
channels were fine.

Also round up or down non-integer division factors. Before, always the
floor value was used.
