test/perf: Add test for TGL OAR unit

Add a test that measures work using MI-RPC for the specific context
without using reports from the OA buffer.

Tigerlake introduces an OA unit that measures work specific to render
workloads. This means we do not have to rely on reports from the OA
buffer to normalize the reports obtained from MI REPORT PERF COUNT
anymore.

v2:
- Add igt_drop_root to make the test run in non-privileged mode (Lionel)
- Move parameter to __perf_open inside the same function (Lionel)

v3, v4:
- Add igt test description
