WebGL test fix for MacOS

On MacOS, the BGRA format is used for framebuffers. Because of that, copying from the BGRA format must be allowed in the same places the RGBA format is allowed. This fixes the following WebGL test on MacOS: conformance/textures/misc/copy-tex-image-2d-formats.html Change-Id: I45c6b81a894dd8d55c4ab5cff0cf9ad1a08c8303 Reviewed-on: https://swiftshader-review.googlesource.com/18348Tested-by: Alexis Hétu <sugoi@google.com> Reviewed-by: Nicolas Capens <nicolascapens@google.com>
