Support using a layer of a texture as a color attachment on OpenGL

This patch implements using a layer of a texture as a color attachment
on OpenGL by using glFramebufferTextureLayer. As WebGPU won't support
rendering into a texture view whose format is different from the
original texture, it is correct to use glFramebufferTexture on the
OpenGL backends.
