Add SECURE_UPGRADE_PROD_TOOL_ARGS flag to make it possible for vendors to pass their own arguments on the prod signing script (#14581)

- Why I did it
Since the prod signing tool is vendor specific, and each vendor may have different arguments they would like to use in the script, we would need a way to inject those arguments to the script.

- How I did it
Add a compilation flag SECURE_UPGRADE_PROD_TOOL_ARGS which vendors can use to inject any flag they would want to the prod signing script.

- How to verify it
Build SONiC using your own prod script
