feat: adopt table-backend-utils into connection monorepo

Adopt keboola/php-table-backend-utils (v4.1.1) from the storage-backend
monorepo into Package/TableBackendUtils. The package continues to be
split to keboola/php-table-backend-utils for external consumers.

- Run adopt-repo.sh to import full git history
- Update root composer.json (replace, autoload, add keboola/php-utils)
- Add CI workflow with lint, Snowflake and BigQuery functional tests
- Add cross-dependency path triggers (SF driver, BQ driver, import-export)
- Add to monorepo_split matrix
- Update PHPStan exclusions
- Update Dockerfile to PHP 8.3
