docs: Add extensions not part of any GL or GL ES version

Based loosely on patches submitted ages ago by Thomas Helland.

v2: Add lots of missing data provided by Ilia.  Fix sort order of
GL_ARB_sparse_texture extensions suggested by Ilia.

v3: Note that Dave Airlie has started work on GL_ARB_bindless_texture.
