For TEST_VISTA test job, add TEST_VISTA_INPUT_SQL cmake variable.
Final Release Note
Description
Right now, for the VistA pipeline, if we want to override the generation of the vista.sql file, we have to put it in a special location so that it won't get generated again and will reuse the already generated file. This was originally done to speed up subsequent tests using the SQL file, as it takes a long time to generate. However, we now have new uses for this, letting us test arbitrary queries with new SQL files. Therefore, we should formalize the process of using a different SQL file than the original one.
