This is part of the Vulkan task T68990. This commits changes a few things: - Rename extensions to capabilities (but left the file name untouched). - Cubemap mip render workaround detection is rewritten using gl commands to avoid using the GPU API before initialization. - Put all the capabilities that are only relevant for the GL backend inside GLContext as static variables. - Cleanup the names of the limit variables. - Separate all GL related workaround search inside the GL module.
