[i-g-t V2 5/8] tests/kms_tiled_display: Test cleanup

[Bhanuprakash Modem]

Make sure the below points in IGT cleanup:

- Sanitize the state before starting the subtest.
- Clear the states before exiting the subtest.
- Update existing libdrm APIs with IGT kms APIs.
- Other misc (Ex: update deprecated APIs/macros/enums, FB leaks etc..)

V2: - Drop few complex fixes
