ab5eb86118 raspberrypi: implement os.urandom 
Since the datasheet cast some doubt on the strength of the "rosc_hw->randombit",
I use the SHA256 hash function to create a high quality random seed
from random values of uncertain entropy, as well as to generate a sequence
of random values from that seed using SHA256 as a cryptographically-secure
random number generator.

In practice, it produces over 100kB/s of random data which does not
have any gross problems according to _PractRand_.

ff1942cff6 Enable protomatter on RP2040 builds 
Also found a race condition between timer_disable and redraw, which
would happen if I debugger-paused inside common_hal_rgbmatrix_timer_disable
or put a delay or print inside it.  That's what pausing inside reconstruct
fixes.

So that the "right timer" can be chosen, `timer_allocate` now gets the `self`
pointer.  It's guaranteed at this point that the pin information is accurate,
so you can e.g., find a PWM unit related to the pins themselves.
This required touching each port to add the parameter even though it's
unused everywhere but raspberrypi.

5423e4966c rp2pio: Transfer up to 32 bytes before checking background tasks 
@Jerryneedell noticed that this problem affected strips short enough
to not use the DMA peripheral, thanks for the hot tip!

Instead of checking for background tasks after every byte transfer,
try up to 32 transfers before attending to background tasks.

This fixes the problem I was seeing on my 5-pixel circuit.

Closes #4135.

6e153d9948 raspberrypi: implement reset, reset_to_bootloader 
This makes all the following work:
 * normal microcontroller.reset()
 * reset into safe mode or UF2 bootloader via microcontroller.on_next_reset()
 * reset into UF2 bootloader via the "1200 baud trick"

The implementation of reset_cpu is from micropython.

Add initial RP2040 support 
The RP2040 is new microcontroller from Raspberry Pi that features
two Cortex M0s and eight PIO state machines that are good for
crunching lots of data. It has 264k RAM and a built in UF2
bootloader too.
