This adds a command which allows an external script to broadcast a
bootloader request, using a supplied UUID to match the request.
Included is a method to process requests to enter the canboot
bootloader.

It's possible for the SCLK pin to still be updating even after the
last byte of data has been read from the receive pin. (In particular
in spi mode 0 and 1.) Exiting early from spi_transfer() in this case
could result in the CS pin being raised before the final updates to
SCLK pin.
Add an additional wait at the end of spi_transfer() to avoid this
issue.

The rp2040 can be flashed without sudo when using udev rules to give the
user permission, but in a standard configuration sudo is required.
Here we make it possible for flash_usb to use sudo for the rp2040
target, and make it the default when using `make flash` for the rp2040.
As for other targets, one can set `NOSUDO=1` to not call through sudo.

This adds `make flash` support for the rp2040 target. Flashing is
performed using a custom `rp2040_flash` tool that uses the PICOBOOT
protocol. Root is not required.
The user specifies the serial device of the rp2040 they wish to flash as
the device. This device is reset into bootsel mode and `rp2040_flash`
is invoked on the original USB device path.
If the device is already in bootloader mode, the user can specify
'first' as `FLASH_DEVICE` which will simply invoke `rp2040_flash` with
no bus/address options.

Unify the handling of the enable_pclock() and is_enabled_pclock() code

on enable_pclock() (this is a change for stm32f0 and stm32h7). The
enable_pclock() code will now also disable irqs during the enable.

Remove the STEP_DELAY Kconfig option and replace it with a per-stepper
step_pulse_duration printer.cfg config option.
The AVR code will continue to have optimized code to step and "unstep"
in the same function (which is automatically activated when the step
delay is 40 ticks or less). This change removes the Kconfig option
for single function step/unstep on 32bit processors.

Some versions of gcc, in some cases, decide that it is OK to move the
read to `INTR` to right after clearing the `SETUP_REC` bit of
`SIE_STATUS`, instead of after the `memcpy`.
The rp2040 datasheet doesn't appear to say anything about how quickly
the `SETUP_REC` bit will be cleared in `INTR`, but regardless the
compiler should not be re-ordering the read like this.
Here we force the correct ordering using a memory barrier.

This commit contains a configuration for the Anycubic Vyper printer from 2021.
It uses a clone of the STM32F103 chip named GD32F103.
There are 2 Mainboard versions out there v0.0.5 and v0.0.6, this config has
been tested with the v0.0.6 only. It should probably work for v0.0.5 as well
since there are no different changes in the Anycubic Marlin firmware.
