(wpss_remoteproc): make SSR optional and add CLI tunables

Default to non-destructive mode (no remoteproc stop/start) and require --ssr
to perform WPSS SSR. Add POSIX-safe argument parsing for --stop-to/--start-to/
--poll-i, and align logging with other remoteproc tests. Keep ath11k fallback
path behavior unchanged.
