tpu-client: Move send_messages_with_spinner from program (#20960)

We have too many ways of sending transactions, and too many
reimplementations of the same logic all over the place.

The program deploy logic and stake-o-matic currently make the
most use of the TPU client, so this merges their implementations into
one place to be reused by both.  Yay for consolidation!
