Revert of Consolidate all touch/gesture related constants in content

Revert of Consolidate all touch/gesture related constants in content (https://codereview.chromium.org/235003005/)

Reason for revert:
Broke content perftest compile, 

http://build.chromium.org/p/chromium.linux/builders/Linux%20Clang%20%28dbg%29/builds/59025

etc...

Original issue's description:
> Consolidate all touch/gesture related constants in content
> 
> InputRouter, TouchEventQueue and GestureEventQueue all use a variety of
> configuration parameters that are littered through the code in a very ad-hoc
> and hard-to-follow fashion.  Consolidate all such parameters into well-defined
> configuration structs, with helper functions to generate the appropriate
> parameters per platform.  This simplifies testing and eases the mental burden
> of tracking down the origin of the various magic constants.
> 
> Note that this change disables scroll gesture debounce by default, enabling it
> only for ChromeOS.
> 
> BUG=343917, 353702
