Add about:instant for under-the-hood instant settings like animation timing
Patch 1 of 2, wires up the chrome://instant page and associated preferences. Attaching the prefs to the actual animations will come in a later CL.
This is based on a blend of chrome://inspect, chrome://gesture_config and chrome://gpu-internals.
BUG=none
TEST=navigate to chrome://instant and click reset, then enter some values
