Fix call target drawable misalignment for sw600-[m|h|xh]dpi.

For those resolutions, the framework ic_lockscreen_handle_pressed
drawable has a different resolutions. Use the same approach to fix it as
DeskClock: Just copy in the framework drawable for the supported
resolutions.

PhoneApp: Initialize ToneGenerator when needed

Whenever there is a radio tech change, mSignalInfoToneGenerator
is released and never created. This leads to phone app crash later
when it is accessed for toneplay. This is fixed by creating the
instance (if null) before calling the APIs.
