Equivalent of log::log_enabled!() for defmt

[ia0]

Are there any plans of having a way to know at compile-time if a given level of logging is enabled? Something similar to log::log_enabled().

This can be useful when a warning should only be displayed if the log level is at least warning and if some run-time condition is fulfilled, but without having to compute the run-time condition if the log level is less than warning.
