Fixes icon and text colors in QS Header to be darker in Light mode.
Also, makes sure that all colors in the icons match.
Does this by implementing the following:
* A new theme that overrides darkIconTheme in Theme.SystemUI by one with
darker colors.
* QuickStatusBarHeader applies that theme and passes is onto its
children, in particular StatusIconContainer/StatusBarMobileView
and BatteryMeterView.
* StatusBarMobileView and BatteryMeterView retrieve the colors from the
theme and apply them accordingly.
* Also applies to QSCarrierGroup
* Additionally, the single color is used for the other icons.
Also invalidates SignalDrawable after setColors is called if at least
one of the colors changed. This is a real issue.
For more info:
* Text and icons set to 70% black on light mode, white in dark mode.
* Dual tone set for background overlaid with fill match single tone.
