* dialect/sql/schema: file based type store
This PR adds support for a file based type storage when using versioned migrations. The file called `.ent_types` is written to the migration directory alongside the migration files and will be kept in sync for every migration file generation run.
In order to not break existing code, where the type storage might differ for different deployment, global unique ID mut be enabled by using a new option. This will also be raised as an error to the user when attempting to use versioned migrations and global unique ID.
Documentation will be added to this PR once feedback on the code is gathered.
