[Pytorch] Build lite interpreter as default for Android

Summary:
Build lite interpreter as default for android, should wait until #56002 lands
Mainly two changes:
1. Use lite interpreter as default for Android
2. Switch the lite interpreter build test to full jit build test

Test Plan: Imported from OSS
