topology: utils: add helper to generate PCM capability 

Add a helper to generate supported formats of the PCM capability, it is
up to the pipeline format:

for s16_le pipeline, only S16_LE is supported.
for s24_le pipeline, both S16_LE and S24_LE are supported.
for s32_le pipeline, all S16_LE, S24_LE and S32_LE are supported.

For each pipeline, we should use CAPABILITY_FORMAT_NAME(PIPELINE_FORMAT)
in the PCM_CAPABILITIES definition.
