feat: generated and identity columns for mssql, sqlite, drizzle, typeorm, bun and gorm readers

- mssql: write computed columns (AS (expr) PERSISTED) and identity; read computed definition and identity - sqlite: write GENERATED ALWAYS AS (expr) STORED; read generated columns via table_xinfo and parse the expression - drizzle: generatedAlwaysAs / generated(Always|ByDefault)AsIdentity, read and write - typeorm: asExpression/generatedType and identity decorators, read and write; decorator scan is now quote-aware - bun, gorm readers: read generated and identity markers - readmes updated
