OpenGL: Add timer query extension detection

Browse Source 
Add detection for GL_EXT_disjoint_timer_query (OpenGL ES) and
GL_ARB_timer_query (desktop GL) extensions. These extensions provide
GPU timestamp queries for profiling render pass durations.

Also adds function pointer declarations for glQueryCounter,
glGetQueryObjecti64v, and glGetQueryObjectui64v.
