feat(mdGesture): perf improvement with disabling of all gesture listeners

[ThomasBurleson]

Use this with following code sample:

app
  .module('myApp',['ngMaterial'])
  .config(['$mdGestureProvider', function($mdGestureProvider) {
    // Useful for environments where swipe and touch events are not important.
    $mdGestureProvider.disableAll();
  }])

Fixes #10884

Please rebase.

I am going to submit another PR with these changes, without the debugger; statement, and without the extra commit.
