Add BigQuery reservation configuration

[max-ostapenko]

This pull request introduces support for specifying BigQuery reservations at both the project and action level, allowing more granular control over query resource allocation. The changes span CLI flags, project configuration, action builders, and test coverage to ensure correct application and precedence of reservation settings.

BigQuery reservation support:

• Added a new --default-reservation CLI flag and corresponding defaultReservation project config option, enabling users to set a default BigQuery reservation for all actions in a project.
• Updated IBigQueryExecutionOptions and BigQueryDbAdapter to accept and propagate a reservation parameter, ensuring reservation information is passed through to BigQuery job execution.

Action-level reservation configuration:

• Extended action builders (Assertion, Table, IncrementalTable, Operation, View) to support an optional bigqueryReservation config property, storing it in the action descriptor for runtime precedence over project-level reservations.

Test coverage and validation:

• Added and updated tests to verify correct application of project-level and action-level reservations, including precedence rules and propagation to compiled outputs.

Project configuration precedence:

• Ensured that action-level bigqueryReservation overrides the project-level defaultReservation at runtime, with tests confirming the correct behavior.

These changes provide users with flexible reservation management for Dataform workload.
