Add common types for audio

These types are migrated from system/audio.h. The order and syntax
of declarations is preserved where available. The following
changes have been made:

 - names changed to satisfy HAL style guide;

 - some previously separate enums grouped into one to allow
   using values between them (HIDL doesn't allow using values
   of one enum in another, and even if it would, that will
   probably be incompatible with C++11 enum classes it generates;

 - as HIDL doesn't have sizeof, these were substituted with values;

 - unions can't contain HIDL string type, thus some names are
   expressed as uint8_t arrays;

 - "handle" is a reserved word in HIDL;

 - HIDL vector type is used instead of count / array pairs;

 - obviously, macros and inline functions not migrated.
