Setup a build matrix for test_android_template (#34355)

Summary:
I'm extending `test_android_template` to use a CI Matrix. This will allow us to make sure that we test a new app template against Debug/Release and against New/Old Arch.

This will make sure we catch a lot of bugs early on 👍

## Changelog
