AVR: target/117681 - Set UNWIND_WORD_MODE to Pmode.

This patch fixes a build warning for libgcc/unwind-sjlj.c
which used word_mode for _Unwind_Word but should use Pmode.

	PR target/117681
gcc/
	* config/avr/avr.cc (TARGET_UNWIND_WORD_MODE): Define to...
	(avr_unwind_word_mode): ...this new static function.
