This fixes some bugs with the resolution of icons for Status Bar and
Navigation Bar by separating the icons into v21 and v11 directories. An
icon is searched in v21 directory by default. For simulating older
platforms, v11 directory is searched first and then v21 is used as a
fallback.
This also adds xxhdpi versions of home, back and recent icons.

LayoutLib can simulate older versions of the platform to a very limited
extent. This change adds the old navigtaion bar icons back and moves the
latest ones to directories suffixed with "-v21". The code handles this
resolution in a very crude way.
This also removes a bunch of unused code and fixes some style warnings.
