firmware: cs_dsp: Add KUnit testing of control read/write 

Add KUnit test cases for control read/write.

Tests cases cover general reading and writing of controls:
1) Read/write at offset position in control.
2) Read/write of various lengths less than length of the control.
3) Rejecting illegal arguments.

The test cases are run for ADSP2 with 16-bit registers, ADSP2
with 32-bit registers and Halo Core with 32-bit registers. The
ADSP2 cases are further divided into runs for V1 and V2 format
WMFW files, because there are differences in how V1 and V2
defines controls.

The obsolete V0 format does not have controls, so no testing of
that format is needed.
