Daniel Lim Wee Soong 3b558eebee Logging: Create logging macros based on fmtlib
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.
