Revert of Do not calculate composition bounds until IME requests. (patchset #11 id:720001 of https://codereview.chromium.org/2121953002/ )
Reason for revert:
CursorAnchorInfoControllerTest.testMonitorMode consistently failing on downstream lollipop bots (and I also see the same failure in the trybots for patchset 11, I don't understand why CQ let this through...).
BUG=633402
Original issue's description:
> Do not calculate composition bounds until IME requests.
>
> Calculating composition bounds is not a light-weight operation.
> On the other hand, few IME uses this information.
> To skip this unnecessary calculation on certain environment, propagate
> cursor update mode from browser to the renderer.
