The OAM unit captures OA reports specific to the media engines. Add support to
program the OAM unit on media tile on MTL.

The OAM unit is selected by passing the class:instance of a media engine to perf
parameters. Corresponding UMD changes are posted to the igt-dev repo as part of
supporting the GPUvis tool.

v2: Incorporate review feedback (Jani, Ashutosh)
