[Sb] Add background and foreground support to icon tints
This CL adds the possibility to tint a status bar icon with both a
background and foreground color. It does this by making the following
changes:
1. Add support for tint and foregroundColor in TintedIconManager
2. Define contrasting colors for DarkIconDispatcher, and add a new
callback that exposes them
3. Support a new interface method (with a default impl) on
StatusIconDisplayable that can accept the foreground tint
As of now, there are no clients of this new tint color. Follow-up CLs
will implement usage on ModernStatusBarMobileView.
Test: compile
Test: visually inspect that icons are the same color
Test: check dumpsys for information from DarkIconDispatcher
