PageInfoController: remove strong ref mContext

Issue:
in PageInfoController, holding mContext is dangerous, because
WebContents' reparenting could cause mContext and mWindowAndroid to be
mismatched.

Change:
Remove mContext as a member of PageInfoController. Instead, get context
from mWindowAndroid when needed.
