In Multi-SIM cases use the color of the SIM icon for InCallUI.

Set the color of the InCallUI to be the color of the SIM icon. In the
single SIM case, the background should be the default background.
* Added id to all call button backgrounds for color change
* Initialize color onResume for InCallActivity
* CallCardFragment/CallButtonFragment/DialpadFragment update their colors
* Added InCallUIMaterialColorMapUtils to extract color
