[WHAT] Add KUnit tests for the failure paths of amdgpu_dm_build_default_pipeline(): a failed allocation and a failed initialization at each of the eight pipeline steps. [HOW] Add struct amdgpu_dm_colorop_kunit_ops, a KUnit-only indirection table for the colorop allocation and the five DRM colorop constructors. The constructors cannot be made to fail through their arguments, so tests install a fake allocator and spies that delegate to the real constructors and override the return value of one selected call. Non-KUnit builds call the same functions directly.
