f46b2e9142 cmArgumentParser: Model maybe-missing string with wrapper type
Bindings to `std::string` require one value.  Some clients have been
filtering `keywordsMissingValue` to support keywords that tolerate a
missing value.  Offer them a type-safe way to achieve this instead.

e6d1e29ffa cmArgumentParser: Model maybe-empty and non-empty lists with wrapper types
Previously bindings to `std::vector<std::string>` required at least one
value.  Some clients have been filtering `keywordsMissingValue` to
support keywords followed by empty lists.  Instead, require clients to
specify whether a keyword's list can be empty as part of the binding
type.
