Bug 1209841 - Send synthesized mouse long tap to gecko. r=automatedtester

Browse Source 
Instead of using long_press_without_contextmenu() with built-in long tap
injector in AccessibleCaretEventHub to select a word, we can use
DOMWindowUtis to send synthesized mouse long tap events to gecko. This
triggers the code path which is closer to the real events fired by APZ
on B2G.

This change also makes marionette tests cover the focus-changing code by
long tap in AccessibleCaretManager. This is subtle but significant since
it's possible to write focus changing tests via long tap now.
