Changing the baudrate requires a complete re-configuration of the Sercom
device, which is put into a separate rather large function. This new
machine_uart_set_baudrate() function will be useful for future drivers such
as Bluetooth.

This replaces the previous make-pin-table.py with an implementation based
on boardgen.py.
- MICROPY_PY_MACHINE_PIN_BOARD_CPU macro is removed. This isn't optional
on other ports, so no need for it to be optional on SAMD.
- pin_af_table is removed, and lookups just search the cpu dict instead
(this saves N*wordsize bytes of firmware size to have this extra table).
- pins.csv is now BOARD,CPU to match other ports.

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.

With public declarations moved to extmod/modmachine.h. It's now mandatory
for a port to define MICROPY_PY_MACHINE_PWM_INCLUDEFILE if it enables
MICROPY_PY_MACHINE_PWM. This follows how extmod/machine_wdt.c works.
All ports have been updated to work with this modified scheme.

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).

This is difficult to implement on cmake-based ports, and having the list
of variants in mpconfigboard.{cmake,mk} duplicates information that's
already in board.json.
This removes the existing query-variants make target from stm32 & rp2
and the definition of BOARD_VARIANTS from the various board files.
Also renames the cmake variable to MICROPY_BOARD_VARIANT to match other
variables such as MICROPY_BOARD. The make variable stays as
BOARD_VARIANT.

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 provides similar functionality to the former zlib.DecompIO and
especially CPython's gzip.GzipFile for both compression and decompression.
This class can be used directly, and also can be used from Python to
implement (via io.BytesIO) zlib.decompress and zlib.compress, as well as
gzip.GzipFile.
Enable/disable this on all ports/boards that zlib was previously configured
for.

In order to keep "import umodule" working, the existing mechanism is
replaced with a simple fallback to drop the "u".
This makes importing of built-ins no longer touch the filesystem, which
makes a typical built-in import take ~0.15ms rather than 3-5ms.

By specifying rts=pin(x) and/or cts=Pin(x) in the constructor. The pad
numbers for the UART pins are fix in this case: TX must be at pad 0, RX at
pad 1, RTS at pad 2 and CTS at pad 3.
repr(uart) shows the pin names for rts and cts, if set. In case of a RX
overflow, the rx interrupt will be disabled instead of just discarding the
data. That allows RTS to act.
If RTS is inactive, still 2 bytes can be buffered in the FIFO.

If sockets were open when calling soft reset, gc_sweep_all() would try to
close them. In case of e.g. the NINA WiFi handler, connected through SPI,
spi_transfer() would be called for command exchange with the NINA module.
But at that time SerCom was already disabled.
Moving sercom_deinit_all() behind gc_sweep_all() solves this issue.
