Add new schema options

[simolus3]

This exposes the new table options introduced in version 0.3.13 of the core extension, namely:

• include_old (either a boolean or an array of column names): Adds an old entry to the ps_crud.data JSON object that includes old values for updates.
• include_old_only_when_changed: Skip unchanged values from updates.
• include_metadata: Adds a _metadata column that can be written to for updates. It's reported through CrudEntry.metadata afterwards.
• ignore_empty_update: Don't create ps_crud entries for UPDATE statements that didn't change any values.

Most of this feature is tested in the core extension, this adds a few simple tests ensuring we forward options correctly.

Changes here LGTM. I think this is good-to-go after we finalize the naming conventions of these new additions.
