Mesa: [windows] Fix for RDP / Chrome Remote Desktop.

This fixesMesa to work properly under Remote Terminal or
Chrome Remote Desktop.

The main issue was that the Mesa WGL backend was still relying
on host GDI32-provided GetPixelFormat() / SetPixelFormat() functions
even though this is not needed. The patch removes this dependency.
