  Add initial support for EXT_disjoint_timer_query.
  
  Basic timer queries are supported and tested in the OpenGL backend
  but are not enabled by default. A good portion of the existing query
  code was also refactored for improved validation - specifically for
  validating that the appropriate extensions are available.
