Allow to translate command synopses
Summary:
Ref T16388
This doesn't technically depend on anything, but only does something useful once D26582 has landed
Test Plan:
Deploy D26582
- Run `bin/config set locale.command en_A*`
- Run various commands and see the synopsis text in all caps
- If D26608 is also deployed then the text "Show this help" will be in all caps. Otherwise it will be in lowercase.
