logging: Extend log_target with call-back for un-formatted log line
Some targets might not want to receive only an opaque, pre-formatted
string, but rather the unformatted arguments with metadata like
sub-system/level/file/line. We solve this by introducing a
log_target->output_raw() function pointer. If a target specifies this
function, it takes precedence over the regular log_target->output()
function.
