[Intel-gfx] [PATCH v6 00/12] Add OAM support for MTL

[Umesh Nerlige Ramappa]

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)
v3: Incorporate review feedback (Jani, Ashutosh)
v4: Incorporate review feedback (Ashutosh)
v5:
- Enforce paired engine-class and engine-instance configuration
- Include fix for Wa_14017512683

v6: Rebase to fix build failure
