Reworked transparent layer
When a halo'ed window is opened, the transparent layer will be always visible. It will manage the background dim.
This fixes some apps dimming its sandboxed processes (like chrome).

LayerActivity manages its own lifecycle. When it's focused after paused it finishes itself.

System processes (identified by "android" pkg in SystemUI and system uid in Activity) don't use the layer and still use their own background. This
has been kept this way to not interfere with their activity.

fix button backlight
TEMPORARY: Reintroduce button-backlight (and respective inactivity timeout)

The power manager rewrite from Change I1d7a52e98f0449f76d70bf421f6a7f245957d1d7
completely removed support for control of the button backlights, which makes
all capacitive buttons out there stay dark. The commit message in that change
mentions it hasn't been implemented _yet_, so this fix should be temporary
until upstream does their own implementation
