Implement support for framebufferOnly render targets.

This reflects Dawn and Metal functionality.
Implement a FramebufferOnly flag on GrSurface and GrBackendRenderTarget.
Forward the state from GrBackendRenderTarget to GrSurface.
Check the GrSurface flag in GrGpu::readPixels() and GrGpu::writePixels()
and early-return.
