raspberrypi: RTC: Ensure a time is set
...
Until a time is set, the RTC is not running, and rtc_get_datetime()
returns false without assigning to the out-parameter.
In CircuitPython, this would manifest as arbitrary values being returned,
since uninitialized storage on the stack was being converted into a timestamp.

raspberrypi: Enable mp3 playback
...
The rp2040 is _very_ marginal for mp3 playback, and currently sometimes triggers a bug that gives garbled audio output. However, it does work for some limited situations.

WIPrp2040: Implement IncrementalEncoder
...
Any two consecutive pins can be used for an IncrementalEncoder
Testing performed: Put a synthesized (few hundred counts per second) quadrature signal into GP2/3 and read the encoder out. Performed filesystem operations at the same time to stress test it.
The reasons for not using common_hal_rp2pio_statemachine_readinto are commented on.

This can be used where the standard API calls for a list of pins, to check that they satisfy the requirements of the rp2pio state machine, e.g.,
```python
def __init__(self, pin_a, pin_b):
if not rp2pio.pins_are_sequential([pin_a, pin_b]):
raise ValueError("Pins must be sequential")

.. all the necessary steps to transform it into a padded, checksummed
file are now done by the build system.
Since it is assigned by "?=", it _should_ be the case that individual
builds can override it.
I did not "test" this per se, but it gives the same content and checksum
(except for the identifying comment with a path) as #4302 .

A few minor fixes for corner cases
...
* Always clear the peripheral interrupt so we don't hang when full
* Store the ringbuf in the object so it gets collected when we're alive
* Make UART objects have a finaliser so they are deinit when their
memory is freed
* Copy bytes into the ringbuf from the FIFO after we read to ensure
the interrupt is enabled ASAP
* Copy bytes into the ringbuf from the FIFO before measuring our
rx available because the interrupt is based on a threshold (not
> 0). For example, a single byte won't trigger an interrupt.

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_.

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.

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 .
