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.

Show as floating window on recent apps

This also removes "hybrid properties" from recents menu, it is fairly unneeded
now. This is a test, It's probable that it will be removed later

Give floating flag to previous activities in the stack
When launching stacked activities, only the last one is flagged as floating in sysui when tapping halo.
This causes the system to show the launcher when the first stacked activity is launched (this first intent gets the flag FLAG_ACTIVITY_TASK_ON_HOME
in TaskStackBuilder).
This change makes all the stacked activities get the floating flag if the last one has it.

Revert removing FLAG_ACTIVITY_CLEAR_TOP from intent
Removing that flag from the intent provokes some apps not being able to finish pressing the back key.
This change doesn't affect other opened apps.

Fix floating window activity result cancellation

Setting Intent.FLAG_ACTIVITY_NEW_TASK on *all* floating window intents
will result in Android dropping activity results for non-new task
activities trying to get results back.
