Commit 7d95a004 introduced a defect - if the cached timer pointed to
by last_insert did not reschedule itself then the cache would not be
in a valid state and other active timers may not get properly
rescheduled.

Add an optimized step function for drivers that support stepping on
both rising and falling edges of the step pin. Enable this
optimization on 32bit ARM micro-controllers. Automatically detect
this capability in the host code and enable on TMC drivers running in
SPI/UART mode.

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.

The previous OSPEEDR value of 0x2 was copied from the stm32f4.c code,
but the stm32f0 interprets that value the same as 0x0 - which is "low"

the configuration of stm32f1 chips.

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.
The LCD is not supported yet (might work, but didn't try yet).

This implements hardware PWM support for the rp2040. The maximum
value(100% duty) is set to 255 to match the other controllers. Cycle
time is clamped automatically, and uses the full 8.4 fractional range of
the rp2040 PWM block. This allows a maximum PWM frequency of 490kHz and
a minimum frequency of 1915 Hz.

The rp2040 doesn't have a chip ID, but the flash chip connected does. We
can get this ID by asking the flash chip directly, but doing so requires
disengaging the XIP layer, performing the interrogation of the flash
chip, and then re-enabling the XIP layer. This gives us a 64-bit unique
ID that we can use as our USB serial number.
