[JIT] Add side effects checks for ops in SchemaInfo subclass (#81002)
- Added has_side_effects method which returns whether a given op has side effects. Currently this is implemented with a hard-coded list of functions copied from ir.cpp in AliasDB, but this will eventually be implemented by returning with a given schema has the has_side_effects tag.
- Tested in test_schema_info.cpp with both an op with side effects and an op without side effects.
