Update GL mailbox synchronization to Chromium 49v5.7.0-alpha1
Chromium 49 switched to using SyncToken, making our old model based on
sync-points obsolete. This patch rewrites our syncing to instead take
advantage of new Chromium API for waiting on sync tokens. It also
moves the creation of the GLFences we use out of Chromium.
