fmt: enable compatibility with fmt>=10

[abouvier]

I have no idea what I'm doing, but this seems to compile fine against both fmt9 and fmt10.
fmt10 basically removed implicit conversions for enums.

Well, it failed spectacularly but at least it works with fmt10 :p

Wouldn't it be easier to add a generic formatter for enums in Common/precompiled.h instead of adding using fmt::enums::format_as in every namespace?
Something like this (or the one that was commented out in precompiled.h):

template <typename Enum>
requires std::is_enum_v<Enum>
struct fmt::formatter<Enum> : fmt::formatter<underlying_t<Enum>>
{
	auto format(const Enum& e, format_context& ctx) const
	{
		return formatter<underlying_t<Enum>>::format(fmt::underlying(e), ctx);
	}
};

And might as well update vcpkg and use fmt 10.0.0 at this point.

It's what fmt::enums::format_as do. But having a generic enum formatter in global namespace causes some errors with fmt9.
