i965: Lift some restrictions on dma_buf EGLImages
Allow glEGLImageTargetRenderbufferStorageOES and
glEGLImageTargetTexture2DOES for dma_buf EGLImages if the image is
a single RGBA8 unorm plane. This is safe, despite fast color clears,
because i965 disables allocation of auxiliary buffers for EGLImages.
Chrome OS needs this, because its compositor uses dma_buf EGLImages for
its scanout buffers.
Testing:
- Tested on Ivybridge Chromebook Pixel with WebGL Aquarium and
YouTube.
- No Piglit regressions on Broadwell with `piglit run -p gbm
tests/quick.py`, with my Piglit patches that update the
EGL_EXT_image_dma_buf_import tests.
