QuickSettings : Register/unregister cast tile one time

Don't do these operations every time the parent is visible/invisible,
it causes jank.

Repro:

Turn on wifi on a network w/ chromecast
Swipe down quick settings panel really fast

QuickSettings : Properly restore lockscreen tile state

The keyguard lock relies on device policy manager service to be active,
currently it fails because it tries to request before its up. Fix that
by registering the request in a receiver

IconPackHelper: Don't respect an icons original size if too large.

  - Otherwise, if an application isn't following app icon guidelines,
  it can create an OOM situation when creating the new icon based
  on the original resource's height and width.
