Summary [chromium] Hold video provider lock from willDraw to didDraw

It's possible for the video provider and frame to go away after willDraw, but before the frame gets uploaded into textures. Since the frame is a raw pointer (that the provider is responsible for), this could cause a bad memory access. Unfortunately, this depends on some other fixes to make sure that we don't ever call willDraw a second time without calling didDraw (which will deadlock on aquiring the exact same lock).
