Re: [PATCH v2 0/6] MR5517: Move wglDescribePixelFormat implementation to opengl32

[Alexandros Frantzis (＠afrantzis)]

v2:
 * Rename `wglDescribePixelFormat` parameters.
 * Use a `PIXELFORMATDESCRIPTOR` member (for now the only one) to store information in `struct wgl_pixel_format`.
 * winewayland: Populate information in `get_pixel_formats` on demand, rather than creating and storing all the info during opengl init. Since we are caching on the PE side this should be fine from an efficiency standpoint, but we can revisit if needed.
 * winex11: Implement `get_pixel_formats` and remove `wglDescribePixelFormat` implementation.
