avrcp: Implement Press/Hold/Release method for MediaPlayer1 This allows us to send any passthrough command, complete with the support to hold down the key. Using Press() will automatically release the key, while using Hold() will keep the key held until an explicit call to Release() is received. This doesn't allow us to hold multiple keys simultaneously, since according to the AV/C Panel Subunit Specification, part 9.4, when the target receive a pressed command without receiving a release command of the previous key, it will be treated as if the release command is sent but not received. Previously, the rewind and fast_forward keys are unique in terms that they are treated as holdable keys, this patch preserves that behavior of calling Rewind() and FastForward(). A rewind event which is reported via the new Press() method will automatically be released instead.
