Replace libUI with native Android AHB API

Replace libUI with native Android AHB API

EGL AHB tests were using libUI which isn't accessible
using public Android builds. This change maps to the
public AHB API in a similar way Vulkan CTS is already
doing.

The supported AHB formats differ from the libUI ones,
so the tested formats have also changed.
