Remove flag to disable cc touch hit testing.

Remove flag to disable cc touch hit testing.

Compositor touch hit testing was re-enabled on Android webview back in February
(https://codereview.chromium.org/183943002) and we haven't had any complaints
since. It's probably safe to remove the flag and related code now.

This is part 1 of 2, will be followed by:
https://codereview.chromium.org/406053002

BUG=304518
Committed: https://src.chromium.org/viewvc/chrome?view=rev&revision=285013

Rick, can you have a quick look? Will add OWNERS after.

[Rick Byers, 2014-07-21 18:44:31]

LGTM

Once this lands, you'll remove the WebKit side too, right?  Probably worth
mentioning in the CL description that this is part 1 of 2.

Yes, I'm rebasing WebKit side CL right now. Will update description.
