tools: tune: Generate ctrl bytes from params for DRC

Used the similar parameter set as the DRC kernel in CRAS to generate ctrl
bytes for DRC component.

Plotted input-output dB response curve with the specific parameter set.

sof: drc: Implement delay only when DRC disabled

Delay the input sample only and don't do other processing. This is used when
the DRC is disabled. We want to do this to match the processing delay of other
bands in multi-band DRC kernel case.

tools: tune: Add tools to generate ctrl bytes for DRC

This commit adds the tools to generate the control bytes for the
drc component. To generate the control bytes, run the example_drc.m
script.

To tweak the parameters modify the values in example_drc.m and run it.

This is still WIP. A fixed set of coefficients is temporarily used in
drc_generate_config.m

sof: drc: Add DRC component with floating-point calculations

This commit adds Dynamic Range Compression (DRC) to the list of SOF
components. DRC in audio processing is intentional to reduce the
volume of loud sounds and amplify the silent sounds as compressing an
audio signal's dynamic range.

This is the intermediate implementation with floating-point calculations.

compile: fix reporting compiler version when built with gcc

Properly retrieve gcc version values and unify the optimisation flag
with Zephyr to always include a '-' in the string. Before this patch
the kernel reports the firmware, built with gcc as

Firmware info: used compiler XCC 12:0:8 xtensa-cnl-elf used optimization flags O2

With this patch it reports

Firmware info: used compiler GCC 8:1:0 xtensa-cnl-elf used optimization flags -O2
