Some data for testing is immutable. In the case, the const qualifier is
available for any loader to place it to read-only segment.

Don't populate the read-only array buf_samples on the stack at
run time, instead make it static const.

At the moment, we have a decent amount of integration tests (selftests)
covering different aspects of the sound subsystem. However, a lot of
of sound-related in-kernel functions remains uncovered. This patch
introduces the KUnit test for the core part of the sound subsystem.
It includes 10 test cases:
- Coverage of the format-related inline functions from 'pcm.h' header
file: snd_pcm_format_physical_width, snd_pcm_format_width,
snd_pcm_format_signed, test_format_endianness
- Coverage of the available bytes counting functions from 'pcm.h'
header: snd_pcm_capture_avail, snd_pcm_playback_avail
- Coverage of functions from pcm_misc: snd_pcm_format_set_silence,
snd_pcm_format_name
- Coverage of card-related functions from init.c: snd_card_set_id,
snd_component_add
This patch depends on the previous patches in this patch series as they
contain fix for the bug, which was found during the test development.
Without them, the test doesn't pass.
