Jesse Hall 6cb7d3dc9f opengl: Regenerate code with ES 3.1 and new extensions
Enable ES 3.1 generation in glgen.py, and regenerate everything to add
support for that as well as these new extensions in the registry:
- EXT_copy_image
- EXT_draw_buffers_indexed
- EXT_geometry_shader
- EXT_gpu_shader5
- EXT_primitive_bounding_box
- EXT_shader_implicit_conversions
- EXT_shader_io_blocks
- EXT_tessellation_shader
- EXT_texture_border_clamp
- EXT_texture_buffer
- EXT_texture_cube_map_array
- EXT_texture_view
