This is the GLES3 sampler object API trivially backported to GLES2, because it allows for simpler/better support in glamor and mutter. The only code change we need is adding these to the generated dispatch tables for ES2 contexts. The interactions with EXT_shadow_samplers, EXT_texture_filter_anisotropic and EXT_texture_sRGB_decode are already in place before this change, and OES_texture_border_clamp is always supported in Mesa.
