Add configuration and feedback implementation necessary to run UAC2
samples on nRF54H20. Limit nRF54H20 to Full-Speed only operation because
the samples currently don't have necessary logic to support High-Speed.

Do not call cache management functions in sample because it does not
work properly if driver uses bounce buffers.

The UAC2 samples do not work with Windows UAC2 driver because:
* driver does not support implicit feedback
* driver expects wMaxPacketSize equal 4 on Full-Speed device
The only correct place to solve these issues is the Windows UAC2 driver.

Convert them to native YAML lists. Support for space-separated
lists was deprecated in Twister a long time ago.

The samples were written when UAC2 class supported only full-speed and
it was not clear how the high-speed would be supported.
Add the full-speed property so the samples can work with updated UAC2
implementation.

The sample illustates how to achieve bidirectional asynchronous audio.
Implicit feedback is the only way to achieve asynchronous USB headset
on devices that have only one isochronous IN and one isochronous OUT
endpoint.
The sample implements stereo playback and mono recording. While it would
be possible to have stereo recording, the commonly available headsets
are mono only. The number of channels can differ between audio sink and
source because the only requirement is that the two run on same clock.
