[PATCH i-g-t v8 0/9] Add writeback changes for intel-supported formats

[Sowmiya S <sowmiya.s@intel.com>]

This series introduces validation for writeback functionality
across newly supported formats specific to Intel platforms.
existing functions with limited format support were retained
for compatibility. After validating new formats introduced by
the platform, additional format support was added to the
writeback test suite. Subtests leveraging common framebuffer
creation logic were consolidated and dynamic subtest generation
was implemented to efficiently handle format-specific variations.
Add negative test cases to validate format and mode.Refactored
existing test cases to improve efficiency.Add helper function
to get the default format.
