LibWeb: Implement GLES2 context creation

Browse source 
For now only macOS is supported.

IOSurface is used as a backing store because it will allow us to read
it from Skia and write to it from OpenGL without any extra copying:
- ANGLE_metal_texture_client_buffer extension is used to create
  EGLSurface from IOSurface.
- Then the same IOSurface is wrapped into Metal texture and passed to
  Skia allowing to share the same memory between Skia Metal backend and
  ANGLE.
