glbuffer: support persistent buffer mappings

Requires OpenGL 4.4 or EXT_buffer_storage

Current mesa exposes GL_ARB_buffer_storage when retrieving the relevant
functions returns no-ops and causes failures.

Improves throughput of uploads by roughly 30%-60% and download throughput by
roughly 10-30% across depending on the exact scenario and hardware.
