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.

Add state machine divisor check
This causes an exception when setting a state machine too slow or
too fast.

Implement audiobusio and enhance PIO for it
This adds I2SOut and PDMIn support via PIO.

StateMachines can now:
 * read and read while writing
 * transfer in 1, 2 or 4 byte increments
 * init pins based on expected defaults automatically
 * be stopped and restarted
 * rxfifo can be cleared and rxstalls detected (good for tracking when
   the reading code isn't keeping up)

Stop-gap solution for #4041. Comment is there to provide info
needed in the future. (We currently run the generic "safe" settings.)

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_.
