common/logging: Make logging get checked at compile time

- ensures log strings match the amount and type (if the format specifies an integer, for example) of the arguments
- if at any later point a runtime-generated string is used as the log format, FmtLogMessage might require an overload taking a fmt::runtime_format_string<> as the format argument type, everything else being equal. wrap the generated string with fmt::runtime() before passing to the LOG_X functio
