Tools: Tune DRC: Export DRC for DMIC capture and cleanup filenames

A DRC blob for capture dmic_default is created. It boosts the capture
by 10 dB when the signal level is low.

The name of speaker blob is changed to speaker_default. The name with
endpoint name first helps to organize them e.g. in UCMv2 blobs data
directories.
