(gpdsp_remoteproc): make SSR optional and add CLI tunables

Default the test to non-destructive mode (no remoteproc stop/start) to avoid
triggering SSR-related wedges. Add POSIX-safe argument parsing and expose
--ssr plus --stop-to/--start-to/--poll-i overrides, matching adsp_remoteproc
behavior. Keep existing DT gating, logging, and result semantics unchanged.
