[Android] Fixes required to get android projects working correctly

[kudaba]

The first commit allows android arm/arm64 and pc win32/win64 builds to live in the same project if you are not using android x86/x64. I do this so I can share a manually curated filters file.

The second commit has a bunch of things I needed to get the projects compiling and deploying properly. It's mostly a rollup of the changes in #100.
