re PR target/50566 ([avr]: Add support for better logging similar to -mdeb)

Browse Source 
PR target/50566
	* config/avr/avr-protos.h (avr_log_t): Add field .builtin.
	* config/avr/avr-log.c (avr_log_set_avr_log): Initialize it.
	Don't bypass TARGET_ALL_DEBUG.  Print self-info with ?.
	(avr_log_vadump): Support %D and %X to print double_int.
	(avr_double_int_pop_digit): New static function.
	(avr_dump_double_int_hex): New static function.
