Add tag-based Item constructors in Structured Headers for string-like values

As well as overloads for `absl::string_view`.

- Prevents accidental implicit conversions from `const char*` and `std::string` that silently defaulted to `kStringType` instead of requiring callers to choose the correct type explicitly, which is important for compliance with specifications using Structured Headers.
- Guarantees at compile time that only valid string-like types are constructed, eliminating runtime `QUICHE_CHECK` assertions on the `ItemType` enum parameter.

This contains no intentional observable behavioral changes.
