Implement CHROMIUM_copy_texture for OpenGL.
This also makes BlitGL work correctly on OpenGL ES (provided vertex
arrays are available)

GL: Emulate SRGB blits where needed.
Desktop OpenGL before 4.4 doesn't handle SRGB blits the same way OpenGL
ES does. Emulate them by drawing a quad.

When doing a LUMA blit, render to an intermediate texture.
Instead of rendering the swizzled result to the destination texture,
render to another intermediate texture and then CopyTexImage it into the
destination texture. Rendering to arbitrary mip levels of the destination
texture is not always supported but CopyTexImage-ing is.

Work around deprecated LUMA formats in the core profile.
Use R and RG textures with swizzle states to emulate them. A manual blit is
required when calling CopyTex[Sub]Image from a RGB[A] framebuffer to an
emulated L[A] texture so that the alpha channel ends up in the correct channel
of the destination texture.
Fixes the following tests when using the core profile:
* conformance/extensions/oes-texture-float.html
* conformance/extensions/oes-texture-half-float.html
* conformance/textures/misc/tex-sub-image-2d.html
* conformance/textures/misc/texture-formats-test.html
* conformance/textures/misc/texture-npot.html
