[Media Common][VP] Add 64-bit semaphore wait support for HEVCe and AV1e scalability

* [Media Common] Add 64-bit hardware semaphore support with fallback
Adds conditional support for MI_SEMAPHORE_WAIT_64 command on platforms with FtrHwSemaphore64 SKU capability. Implements INIT_MHW_MI_SEMAPHORE_WAIT_64_PARAMS macro to initialize 64-bit semaphore parameters with semaphoreToken hardcoded to 0 and context switch inhibition enabled. Falls back to existing MI_SEMAPHORE_WAIT for platforms without 64-bit support.
