Reland "Reland "ozone/drm: Render primary framebuffers as RGBA""

This reverts commit 7c475ee71ef38604a435b9027dd47d8462337344.

Reason for revert: We've fixed the issue where eglCreateImageKHR fails with ARGB+AFBC and reverted CL:985033 which enabled blending for the lowest order plane, which doesn't work everywhere.
