This commit adapts the stm32 port to allow switching from STM USB stack to
TinyUSB stack.
Using TinyUSB improves consistancy with other MicroPython ports and brings
in the ability to use the runtime USB definition support recently added to
other TinyUSB based ports.
By default the existing STM USB stack is used. TinyUSB can be enabled in a
board configuration with:
#define MICROPY_HW_TINYUSB_STACK (1)
Or, it can be enabled from the command line with:
make -C ports/stm32 CFLAGS_EXTRA='-DMICROPY_HW_TINYUSB_STACK=1'

This commit adds preliminary support for ST's new STM32N6xx MCUs.
Supported features of this MCU so far are:
- basic clock tree initialisation, running at 800MHz
- fully working USB
- XSPI in memory-mapped mode
- machine.Pin
- machine.UART
- RTC and deepsleep support
- SD card
- filesystem
- ROMFS
- WiFi and BLE via cyw43-driver (SDIO backend)
Note that the N6 does not have internal flash, and has some tricky boot
sequence, so using a custom bootloader (mboot) is almost a necessity.

The H7 has a hardware UART FIFO, so it's worth enabling it, to reduce the
chance of missed incoming characters. Note that `HAL_UART_Init(&huart)`
does not activate the FIFO, it must be done explicitly by calling
`HAL_UARTEx_EnableFifoMode(&huart)`.

The cyw43-driver now provides the Bluetooth initialisation code, making
`drivers/cyw43/cywbt.c` obsolete. To use the new code a port must enable
the `CYW43_ENABLE_BLUETOOTH_OVER_UART` option.
Some ports have yet to migrate to the new code, so in the meantime they can
explicitly add the old source to their source list and continue to use it
without change.

This commit implements `vfs.rom_ioctl()` to query, erase and write both
internal and external flash, depending on how the board configures its
flash memory.
A board can configure ROM as follows.
To use internal flash memory:
#define MICROPY_HW_ROMFS_ENABLE_INTERNAL_FLASH (1)
To use external flash memory (QSPI memory mapped):
#define MICROPY_HW_ROMFS_ENABLE_EXTERNAL_QSPI (1)
#define MICROPY_HW_ROMFS_QSPI_SPIFLASH_OBJ (&spi_obj)
Then the partition must be defined as symbols in the linker script:
_micropy_hw_romfs_part1_start
_micropy_hw_romfs_part1_size
And finally the partition needs to be enabled:
#define MICROPY_HW_ROMFS_ENABLE_PART1 (1)
There's support for a second, optional partition via:
_micropy_hw_romfs_part2_start
_micropy_hw_romfs_part2_size
#define MICROPY_HW_ROMFS_ENABLE_PART1 (1)

This allows UART RX to function while flash erase/writes operations are
under way, preventing lost serial data so long as it fits in the UART RX
buffer.
This enables (among other things) mpremote to successfully copy files to
boards that use a UART REPL.
Enable via the following option placed in `mpconfigboard.mk`:
MICROPY_HW_ENABLE_ISR_UART_FLASH_FUNCS_IN_RAM = 1

With LAN8742, LAN8720, LAN83825 and DP83848 as possible options, and the
symbols PHY_LAN8720, PHY_LAN8742, PHY_DP83825 and PHY_DP8348. The default
is PHY_LAN8742 which is the existing behaviour.
The eth_init() parameters for the Portenta H7 board are set to phy_addr=0
and phy_type=LAN8742, which matches the previous defaults and the
schematics.
Tested with LAN8720 and DP83848 breakout boards at 10M Duplex and 100M
Duplex modes.

This is a code factoring to have the dict for the machine module in one
location, and all the ports use that same dict. The machine.soft_reset()
function implementation is also factored because it's the same for all
ports that did already implement it. Eventually more functions/bindings
can be factored.
All ports remain functionally the same, except:
- cc3200 port: gains soft_reset, mem8, mem16, mem32, Signal; loses POWER_ON
(which was a legacy constant, replaced long ago by PWRON_RESET)
- nrf port: gains Signal
- qemu-arm port: gains soft_reset
- unix port: gains soft_reset
- zephyr port: gains soft_reset, mem8, mem16, mem32

All ports now use `--board-csv`, `--prefix`, `--output-souce`,
`--output-header` and no longer write to stdout. This matches the esp32
implementation.
Ports that have an AF input use `--af-csv` (to match `--board-csv`).
Any additional output files are now prefixed with `output-` (e.g.
`--output-af-const`).
Default arguments are removed (all makefiles should always specify all
arguments, using default values is likely an error).
Replaced the `af-defs-cmp-strings` and `hdr-obj-decls` args for stm32 with
just `mboot-mode`. Previously they were set on the regular build, now the
logic is reversed so mboot sets it.

It's not supported on all ports, adds complexity to the build to generate
pins_af.py, and can mostly be replicated just by printing the pin objects.
Remove support for generating pins_af.py from all ports (nrf, stm32,
renesas-ra, mimxrt, rp2).

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

- I2S class definition and method table.

- The make_new code.

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 drops the `.cpu` directive from the ARM gchelper_*.s files. Having
this directive breaks the linker when targeting older CPUs (e.g. `-mthumb
-mthumb-interwork` for `-mcpu=arm7tdmi`). The actual target CPU should be
determined by the compiler options.
The exact CPU doesn't actually matter, but rather the supported assembly
instruction set. So the files are renamed to *_thumb1.s and *thumb2.s to
indicate the instruction set support instead of the CPU support.
