lib/igt_fb: Add support for allocating T-tiled VC4 buffers
This introduces the required bits for allocating buffers with a T-tiled
disposition, that is specific to the VC4. It includes calculating the
top-tile width and creating a buffer object with the VC4-specific
helper. The tiling flag is set to the buffer object so that this can
be reused for GPU tests if needed later.
