Fix build: wrap logged enums with fmt::underlying

[thotypous]

With fmt v10+, build currently fails:

/usr/include/spdlog/logger.h:140:12:   required from ‘void spdlog::logger::info(fmt::v11::format_string<T ...>, Args&& ...) [with Args = {const unsigned int&, const hal::module_identification::MultithreadingPriority&}; fmt::v11::format_string<T ...> = fmt::v11::fstring<const unsigned int&, const hal::module_identification::MultithreadingPriority&>]’
  140 |         log(level::info, fmt, std::forward<Args>(args)...);
      |         ~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
/hal-emsec/plugins/module_identification/src/api/module_identification.cpp:409:17:   required from here
   70 | #define log_info(channel, ...) LOG_CHANNEL(channel)->info(__VA_ARGS__)
      |                                                          ^
/usr/include/fmt/base.h:2235:45: error: ‘fmt::v11::detail::type_is_unformattable_for<hal::module_identification::MultithreadingPriority, char> _’ has incomplete type
 2235 |     type_is_unformattable_for<T, char_type> _;
      |                                    

It turns out it is now needed to wrap enums with fmt::underlying. See also https://stackoverflow.com/a/77751342/13649511.
