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.

Saves 71 bytes of bytecode.

This makes fill() about 7x faster (PYBV11 and PYBD_SF6) for the cost of +40
bytes of bytecode (or 120 bytes text).

* For boards a with reset switch, pressing twice resets into bootloader.
* Enabled by linking with the pico_bootsel_via_double_reset library.

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 feature {x=} was introduced in Python 3.8 so needs a separate .exp
file to run on earlier Python versions.

This makes it work like --no-follow and --no-exclusive using a mutex group
and dest.  Although the current implementation with BooleanOptionAction is
neater it requires Python 3.9, so don't use this feature.

You can set one or the other (or neither) but not both.

The --no-exclusive flag was accidentally added to the mutex group in
178198a0.

The --soft-reset flag was accidentally added to the mutex group in
41adf178.

These flags can be specified independently to --[no-]follow so should not
be in that mutex group.

This achieves a substantial performance improvement when rendering glyphs
to color displays, the benefit increasing proportional to the number of
pixels in the glyph.

The compiler was optimising this out already so it's a no-op change.

And using "-B" means mpy-cross is forcefully rebuilt, sometimes with
invalid CFLAGS_EXTRA options which makes the auto-build fail.

This is a generic API for synchronously bit-banging data on a pin.

Initially this adds a single supported encoding, which supports controlling

The sys.stdin.buffer and sys.stdout.buffer streams work just as well (and
are just as fast) as pyb.USB_VCP on stm32 devices, so there's no need to
have the USB_VCP specialisation code, which just adds complexity.

Also, on stm32 devices with both USB and UART (or other serial interface),
if something other than the USB_VCP port is used for the serial connection
then mpremote mount will not work because it will default to reading and
writing on USB_VCP instead of the other connected serial stream.

As part of this simplification, support for a second port as input is
removed (this feature was never exposed to the user).

This was missed in 692d36d7.  It's not
strictly necessary as the GC will clean it anyway, but it's good to
pre-emptively gc_free() all the blocks used in lexing/parsing.

Prevents the finaliser from being missed if there's a dangling reference
on the stack to one of the blocks for the files (that this test checks
that they get finalised).
