Provides the implementation of utilities to convert between HIDL format of data types used in Offload HAL service and the format used by CHRE. Added unit tests to verify conversions. Bug: 32842314 Test: VTS and Unit tests Change-Id: I26a1d9a8efe68cdacacd8226d0739ad40d2b339f Merged-In: I26a1d9a8efe68cdacacd8226d0739ad40d2b339f
