Initialize `static constexpr` tag members in `structured_headers.h`

Add `{}` direct-list-initializers to the `string`, `token`, and `byte_sequence`
tag members in `Item` and `ItemView`, and drop the redundant `inline` specifier
since `static constexpr` class members are implicitly `inline` since C++17.

C++ requires in-class `static constexpr` members to have an explicit initializer
(`{}` or `= ...`), even for empty structs. Clang accepts omitting it as an
extension, but GCC rejects it.
