[CmdPal][Calc] Add option to choose Copy as the primary command (close on enter) (#40398)

## Summary of the Pull Request
Adds a new setting that lets users swap Save/Copy as primary/secondary
commands. This is done in order to enable closing on enter (similar to
PTRun) and therefore saving three extra steps (see issue). Defaults to
true - Copy is primary.
