Drift 2.11.1

This minor drift release contains bug fixes and performance improvements for the builder:

• Allow references to sqlite_schema in drift files.
• Support the timediff and octet_length functions from sqlite 3.43.0.
• Reduce the amount of assets read by drift, improving build performance and enabling faster incremental rebuilds.
• Fix missing import references around @UseRowClass with generateInsertable: true when modular code generation is enabled.
• Allow using .read() for a column added to a join from the table, fixing a regression in drift 2.11.0.
• Make step-by-step migrations easier to customize with Migrator.runMigrationSteps.
