Use system/audio to/from string converters in TypeConverter

Use of system functions eliminates the need for listing all enum
values in TypeConverter tables.

Slight changes in the converting functions:

1. 'channelMaskFromString' function now also accepts indexed
   masks.
2. Fixed UB in 'formatFromString' function.
3. Removed 'deviceFromString' function, use
   'DeviceConverter::fromString' instead.

Replaced direct includes of 'system/audio-base.h' with
includes of 'system/audio.h'.
