base: simplify OmniSwitch recents

The handshake between SystemUI and OmniSwitch is nice
but causes issues if one of the parts gets restarted
thanks to android. So simplify it and only use the
settings value. Worst thing that can happen is that
OmniSwitch recents is enabled but OmniSwitch is not running
then nothing will happen if recents is triggered

allow forcing HighEndGfx mode

people have already started fipping the lowRam prop to enable
transparent status bar, this will enable it with fewer
repercussions.

Add persist.sys.force_highendgfx=true for enable it with enabled lowram.
