Load only gl 3.3 functions
This commit makes 'gl::load_with' only load symbols from the minimal OpenGL (3.3) version alacritty aims to support. Doing so reduces the size of gl_bindings.rs from 21K LoC to 11K LoC, and also the actual loading by up to ~2x, thugh the loading is usually sub millisecond anyway.
