Add int32_t as required type to some operators  (#7192)

* Updates to some operators to always support int32 and int64 based on testing of Android package build config with a minimal build.

If an operator can be used for shape manipulation (int64) it is frequently used for indices manipulation (int32), so we enable both types for that set of ops.
  - e.g. BERT models take indices as input
  - Scatter/Gather ops utilize indices

Misc. fix to python bindings to exclude call that fails in a minimal build.
