Auto merge of #23294 - ceyusa:playerglcontext, r=ferjm,jdm

Update Player instantiator API

Now servo/media player requires a new parameter for its creator, which is a trait object that provides the GL parameters needed for setup the generation of frames as GL textures.

This patch provides a dummy GL context trait object where the code path will go to the default of raw frames.
