Jeff Epler 6d97f6fccc audioio: Remove compatibility code
These items were aliased from audiocore to audioio for compatibility
with 4.x, but according to our deprecation schedule can be removed
in 6.0.

Jeff Epler 47d6dd843e audioio: By default, be compatible with 4.x
Testing performed: That the shipped .mpy files on a PyPortal (CP 4.x)
still work (play audio) with this branch, instead of erroring because
`WaveFile` can't be found in `audioio`.

Flash usage grew by 28 bytes.  (I expected 24, there must be some other
effect on size/alignment that I didn't predict)

Jeff Epler 6b44e40ee8 audiocore: Factor from audioio
When nrf pwm audio is introduced, it will be called `audiopwmio`.  To
enable code sharing with the existing (dac-based) `audioio`, factor
the sample and mixer types to `audiocore`.

INCOMPATIBLE CHANGE: Now, `Mixer`, `RawSample` and `WaveFile` must
be imported from `audiocore`, not `audioio`.

Introduce audioio.Mixer which can mix multiple audio samples
to produce a single sample.

Only works with 16 bit samples on the M4.

Fixes #987

Scott Shawcroft 28642ab10d Add audio output support!
This evolves the API from 2.x (and breaks it). Playback devices are now
separate from the samples themselves. This allows for greater playback
flexibility. Two sample sources are audioio.RawSample and audioio.WaveFile.
They can both be mono or stereo. They can be output to audioio.AudioOut or
audiobusio.I2SOut.

Internally, the dma tracking has changed from a TC counting block transfers
to an interrupt generated by the block event sent to the EVSYS. This reduces
the overhead of each DMA transfer so multiple can occure without using up TCs.

Fixes #652. Fixes #522. Huge progress on #263
