This commit refactors machine.PWM and creates extmod/machine_pwm.c. The
esp8266, esp32 and rp2 ports all use this and provide implementations of
the required PWM functionality. This helps to reduce code duplication and
keep the same Python API across ports.
This commit does not make any functional changes.

The zephyr port doesn't support SoftI2C so it's not enabled, and the legacy
I2C constructor check can be removed.

To keep things neat and tidy, we ensure that each file has 1 and only 1
newline at the end of each file.

A board can now define the following to fully customise the extended block
device interface provided by the storage sub-system:
- MICROPY_HW_BDEV_BLOCKSIZE_EXT
- MICROPY_HW_BDEV_READBLOCKS_EXT
- MICROPY_HW_BDEV_WRITEBLOCKS_EXT
- MICROPY_HW_BDEV_ERASEBLOCKS_EXT

Add a new board type for ESP32-C3 revision 3 and up that implement the USB
serial/JTAG port on pin 18 and 19. This variant uses the USB serial for
programming and console, leaving the UART free.
- Pins 18 and 19 are correctly reserved for this variant. Also pins 14-17
are reserved for flash for any ESP32-C3 so they can't be reconfigured
anymore to crash the system.
- Added usb_serial_jtag.c and .h to implement this interface.
- Interface was tested to work correctly together with webrepl.
- Interface was tested to work correctly when sending and receiving
large files with ampy.
- Disconnecting terminal or USB will not hang the system when it's
trying to print.
Flash erase/program functions disable the XIP bit. If any code runs from
flash at the same time (eg an IRQ or code it calls) it will fail and cause
a lockup.
This compiler is unable to optimise out the giant strcmp match generated
by MP_MATCH_COMPRESSED.

This allows the write to trigger a notification or indication, but only to
subscribed clients. This is different to gatts_notify/gatts_indicate,
which will unconditionally notify/indicate.

This implements (most of) the PEP-498 spec for f-strings and is based on
https://github.com/micropython/micropython/pull/4998 by @klardotsh.
It is implemented in the lexer as a syntax translation to `str.format`:
f"{a}" --> "{}".format(a)
It also supports:
f"{a=}" --> "a={}".format(a)
This is done by extracting the arguments into a temporary vstr buffer,
then after the string has been tokenized, the lexer input queue is saved
and the contents of the temporary vstr buffer are injected into the lexer
instead.
There are four main limitations:
- raw f-strings (`fr` or `rf` prefixes) are not supported and will raise
`SyntaxError: raw f-strings are not supported`.
- literal concatenation of f-strings with adjacent strings will fail
"{}" f"{a}" --> "{}{}".format(a) (str.format will incorrectly use
the braces from the non-f-string)
f"{a}" f"{a}" --> "{}".format(a) "{}".format(a) (cannot concatenate)
- PEP-498 requires the full parser to understand the interpolated
argument, however because this entirely runs in the lexer it cannot
resolve nested braces in expressions like
f"{'}'}"
- The !r, !s, and !a conversions are not supported.
Includes tests and cpydiffs.

This commit creates a new stm32 board for the NUCLEO_H743ZI2, which is the
current version of this from ST. This is a modified copy of the
NUCLEO_H743ZI board, and the ZI2 board differs in a few minor ways:
- LED2 has moved from PB7 to PE1 and is now yellow rather than blue
- the USB power enable has moved from PG6 to PG10
- the USER button is now pulled down
This function can be used to enable and disable the DC/DC converter with or
without the Bluetooth stack enabled. It can also be used to query the
current state of the DC/DC.
This commit also adds a definition of ARRAY_SIZE needed by nrfx HAL-layer.
extmod/vfs_lfs.c needs to resolve `mp_hal_time_ns()` in order to calculate
a timestamp from 1970 epoch. A wall clock is not available in the nrf
port, hence the function is implemented to resolve compilation linkage
error. The function always return 0.
Set the default manifest to "modules/manifest.py". This includes files
from the folder "modules/scripts". The manifest default value is overriden
by all nrf51 boards that have SoftDevice present (SD=s110) to save flash.
Also add "modules/manifest.py" which is set to freeze
"modules/scripts/_mkfs.py".
Add a helper script _mkfs.py which automatically formats the file system if
nrf.Flash() is located and a VFS file system has been included in the
compilation.
The precedence is: first LFS1, LFS2 then FAT.
Update the Makefile to handle FROZEN_MANIFEST, and the README with some
small samples on how to use freeze manifests. And add BOARD_DIR to the
Makefile which can be referenced in boards/<board>/mpconfigboard.mk to
include a board specific manifest.
Enable the following features for all boards except
nrf51 boards with SoftDevice present:
- MICROPY_VFS
- MICROPY_PY_NRF
- MICROPY_HW_ENABLE_INTERNAL_FLASH_STORAGE
