9797e39e - [Option] Add OptionalValueField, OptionalEnumField, and list fields (#230812)

[Option] Add OptionalValueField, OptionalEnumField, and list fields (#230812) OptionalValueField and OptionalEnumField declare a std::optional member, staying std::nullopt if unspecified. ListField declares an ArrayRef member replacing a cl::list with cl::CommaSeparated: each occurrence appends its comma-separated values, keeping the struct trivially destructible. The elements live alongside the argument copies, in the BumpPtrAllocator that cl::LibraryOptions::parse now takes, until the next reset. EnumListField maps the values to enumerators as EnumField does. Aided by Opus 5.5
