[PATCH i-g-t v5 00/10] tests/imagination: Add initial test coverage for Imagination DRM driver

This series introduces a new Imagination-specific
set of tests covering core driver functionality exposed through GEM and
IOCTL interfaces. The tests focus on validating userspace-visible APIs.
 
The series includes:
 
  - Imagination test framework
  - GEM mmap coverage
  - DEV_QUERY API validation
  - GPU ID verification
  - Heap information tests
  - Static data area tests
  - VM context tests
  - Free list creation tests
  - HWRT creation tests
  - Runtime information tests
  - Quirks and enhancements query tests
 
This establishes the foundation for future Imagination driver testing.
