Power: Add multimedia hints

Add hints for video encode and decode use cases. These
hints are sent when the relevant use case starts and ends.
Clients can also send metadata along with the hint to provide
context to the power HAL so that it can make more informed
decisions about how to tweak system-level parameters.
