Now that the project targets C++23, use the standard library's
std::expected instead of the vendored tl::expected polyfill:
- tl::expected -> std::expected, tl::unexpected/tl::make_unexpected -> std::unexpected
- .map()/.map_error() -> .transform()/.transform_error()
- #include <expected.hpp> -> #include <expected>, grouped with std headers
- Remove 3rdParty/tl/expected.hpp (the tl target remains for function_ref.hpp)

* Add Lua towner API and dynamic dialog options
Expose TownerShortNames to Lua (devilutionx.towners), per-towner position
helpers, and RegisterTownerDialogOption for mod-driven store dialog lines.
Includes stores integration and tests.
Also renames lua/lua.hpp to lua/lua_global.hpp.
The previous name broke version auto-detection in sol2, which involves
calling `__has_include(<lua/lua.hpp>)`.
