[WebLayer] Remove PageInfoController deps on Profile, ChromeActivity.

PageInfoControllerDelegate has been introduced to allow customization of
PageInfoController java code, currently focussing on everything that
requires Profile or ChromeActivity.

The end goal is to have no chrome dependencies in PageInfoController so
it can be moved to //components.
