Support for using custom types as tables ids

[zhurs]

Sometimes it is suitable to use custom types as table ids (however test example is synthetic).
Right now a lot of operations fail with exception:

Can't infer the SQL type to use for an instance of org.jetbrains.exposed.sql.tests.shared.entities.CityId. Use setObject() with an explicit Types value to specify the type to use.
org.postgresql.util.PSQLException: Can't infer the SQL type to use for an instance of org.jetbrains.exposed.sql.tests.shared.entities.CityId. Use setObject() with an explicit Types value to specify the type to use.

Thank you for highlighting the issue, we definitely have lack of tests for custom columns, so problems like this appear.

Right now I'm working on the column transforms feature #2143 and it could be also interesting to check if we can use transformed columns as IDs.

Anyway, what you mentioned should be fixed.
