Adds ldn services based off information provided by Switch Brew.

A few inclusions were being satisfied indirectly. To prevent breakages
in the future, include these directly.

These can just use a view to a string since its only comparing against
two names in both cases for matches. This avoids constructing
std::string instances where they aren't necessary.

Now that the old macros are no longer used, we can remove all functionality related to them.

Additionally, when updating fmtlib, there was a change in fmtlib broke
how the old logging macro was overloaded, so this works around that by
just naming the fmtlib macro impl something different

Due to premature merging of #262 I think the build may be failing right now. Should merge this ASAP to fix it.

service: Initialize NFP service.

Log: Add NFP service as a log subtype.

Add a new set of logging macros based on fmtlib
Similar but not exactly the same as https://github.com/citra-emu/citra/pull/3533

Citra currently uses a different version of fmt, which does not support FMT_VARIADIC so
make_args is used instead. On the other hand, yuzu uses fmt 4.1.0 which doesn't have make_args yet
so FMT_VARIADIC is used.
