_mjit_compile_send.erb: simplify control flow

to introduce additional optimization for another `cc->me->def->type`
later. I carved out the `cc->me->def->type == VM_METHOD_TYPE_ISEQ`
part because I wanted to check other types as well.

mjit_compile.c: drop get_iseq_if_available and define simplified version
of it, has_valid_method_type.
