WebGL: Validate simple rendering feedback loops.

This adds the most basic form of rendering feedback loop detection:
when we're rendering to a texture that's also bound as an input. It
doesn't filter by selected mipmap level or 3D texture slice, or
do depth attachment validation. It also is missing checks for feedback
loops against the default Framebuffer.
