This is used by Mus. Any reason not to update this too? Thanks!

I am not sure GPU VSyncProvider could be used with mus. Take a look at
https://codereview.chromium.org/2626413002/diff/60001/content/browser/composi...
which is from a pending change that shows integration of this feature on the
compositor side. It specifically avoids turning GPU v-sync in the case of mus.
Whether or not this could be used with mus we should discuss.
