Pass BOOL values as real types (int/bool) instead of strings to SQL parameters. (#101961)

* Pass BOOL values as real types (int/bool) instead of strings to SQL parameters.

Fixes following integration tests when running with Spanner:
* TestIntegrationDataAccess
    * GetDataSourcesByType/Get_prunable_data_sources
* TestIntegrationUserAuthToken:
    * expires_correctly
    * can_properly_rotate_tokens
    *  keeps_prev_token_valid_for_1_minute_after_it_is_confirmed

* Fix more places where "true" or "false" string was passed as query parameter instead of bool value.

* Removed unit test because it brought unwanted dependencies on xorm into multiple modules.
