Explore the possibility of generic `SqlToGcsOperator`

### Body Recently `SqlToS3Operator` was added in PR https://github.com/apache/airflow/pull/20807 (It also deprecated `MySqlToS3Operator`) In Google provider Currently we have [BaseSQLToGCSOperator](https://github.com/apache/airflow/blob/1b568d73e1dfb838a3a0446e3a6063b9f27f04b8/airflow/providers/google/cloud/transfers/sql_to_gcs.py#L36) with `PrestoToGCSOperator`, `MSSQLToGCSOperator`, `MySQLToGCSOperator`, `OracleToGCSOperator`, `PostgresToGCSOperator`, `TrinoToGCSOperator`, `DummySQLToGCSOperator` This task is to check if we can have a generic `SqlToGCSOperator` just like there is for AWS so we won't need class per each provider... ### Committer - [X] I acknowledge that I am a maintainer/committer of the Apache Airflow project.
