lib/string_choices: Introduce several opposite string choice helpers

Similar to the exists helper: str_enable_disable/
str_enabled_disabled/str_on_off/str_yes_no helpers, we can
add the opposite helpers. That's str_disable_enable,
str_disabled_enabled, str_off_on and str_no_yes.

There are more than 10 cases currently (expect
str_disable_enable now has 3 use cases) exist in the code
can be replaced with these helper.
