issue #10831: added --with-memo option to all cli commands that submit (#16291)

* issue #10831: added --with-memo option to all cli commands that submit
transactions.  Also, improve the block command to show UTF-8 string instead
of integer values for memo program data.

* Fixed tests and changed some syntax according to feedback.

* Use spl_memo id (all versions where applicable) instead of hardcoding id.

* Update Cargo.toml in programs/bpf.

* Update formatting via cargo fmt.

* Update to use spl_memo version 3.0.1, which simplifies package imports
