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.

For first run, allocated memory pointer has been written twice to
config->filter_config but freed only once - memory leak.

logger: fix uninitialized FILE *out_fd in filter_update_firmware()

Reported by VERBOSE=1 CMAKE_BUILD_TYPE=Release ./scripts/build-tools.sh -l
and gcc version 9.3.0-10ubuntu2.

out_fd is not initialized on the first "goto err:" and this can result in
trying to close a random file descriptor.

Fixes commit 126060ae633b ("logger: Send parsed runtime log levels to FW
via debugFS")

test: pcm converter: Utilize comp_buffer implementation instead of mocking

Currently pcm converter unit tests use mocked-up audio_stream
implementation which should be replaced with real FW implementation.
