Build native android graphics library for desktop 

The purpose of this is to be able to use the native graphics code from
the Android platform directly in Android Studio (running on desktop) to
do layout rendering.

This creates a host library that is a subset of libandroid_runtime
including only the JNI files relevant to Android graphics. It also
includes LayoutlibLoader.cpp which is used to load the JNI when using
it as part of layoutlib (the graphics library for Android Studio).

This also creates libhwui-host, a host library that is a subset of
libhwui.

Bug: 117921091
Test: lunch sdk && m libandroid_runtime
