Add --block-{verification,production}-method flags (noop atm) (#30746)

* Add --{replaying,banking}-backend flags (noop atm)

* Greatly simplify enums with strum

* Update programs/sbf/Cargo.lock...

* Rely on Display, removing Debug

* constify cli_names()

* Don't allow omitting bankend value

* Rename to --block-{verification,production}-method

* Use more specific name

* Actually support missing value....

* Remove strictly-unnecessary flags

* Use lazy_static! instead of abusing DefaultArgs...
