Mark rtl_avoid_store_forwarding functions final override

It is customary to mark the gate and execute functions of the classes
representing passes as final override but this is missing in
pass_rtl_avoid_store_forwarding.  This patch adds it which also
silences a clang warning about it.

gcc/ChangeLog:

2025-06-24  Martin Jambor  <mjambor@suse.cz>

	* avoid-store-forwarding.cc (class
	pass_rtl_avoid_store_forwarding): Mark member function gate as
	final override.
