## Description
Fixes#7492
In order to run createMigration, we need to read in the previous
snapshot file if one exists. When that snapshot was generated from an
older version of drizzle-kit, we have to first migrate it up match the
latest version for drizzle to generate the new migration. This change
adds in the call to check the version and migrate the snapshot if
needed.
- Abstract shared sql code to a new drizzle package
- Adds sqlite package, not ready to publish until drizzle patches some
issues
- Add `transactionOptions` to allow customizing or disabling db
transactions
- Adds "experimental" label to the `schemaName` property until drizzle
patches an issue
