Enable support for audio HAL V7 in the framework

Update code in libaudiohal to augment it for the changes
in the data types.

Moved some conversion code out into a new effect utils
library under hardware/interfaces.

Renamed VersionUtils.h to ParameterUtils.h to avoid
file name clash with the file from hardware/interfaces.
