Pass |context_state| in SharedImageRepresentationSkiaGL::Create.

A recent change -
https://chromium-review.googlesource.com/c/chromium/src/+/1783526
requires |context_state| to be passed to
SharedImageRepresentationSkiaGL::Create().
This started causing nullptr deref crashes since it was passed as
nullptr before in SharedImageVideo.
