[OpenMP,MLIR] Translation of parallel operation: num_threads, if clauses 3/n

[kiranchandramohan]

Summary

This simple patch translates the num_threads and if clauses of the parallel operation. Also includes test cases.

A minor change was made to parsing of the if clause to parse AnyType and return the parsed type. Updates to test cases also.

:) Thanks. Is it OK if this is changed when we add support for cancellation?
