[export] Serialize constrain_as_size ops (#107386)
Since constrain_as_size has been fixed, I tried serializing it, but ran into some issues.
Notably, after each `.transform` call, I added a helper `_get_updated_range_constraints` to update the range constrains list. This is because when we retrace in a pass, the symbolic values being used changes, so we need to update this dictionary.
