The "webgl/webgl2.h" include provides that function, but it's not available in emscripten versions < 2.0.17 . Since we need to support emscripten 1.39.9 (mono builds), this commit adds a JS function in library_godot_display.js as a compatibility layer for it, and implement glGetBufferSubData by funneling the call to that function (so we don't have name collisions JS-side with recent emcc). All those hacks are now moved to the platform directory instead of being ifdefs inside the drivers implementations.
