merge revision(s) 54168: [Backport #12391]

	* bignum.c (rb_big_hash): make it public function to be available in
	  other source files, and remove documentation comment for Bignum#hash.

	* bignum.c (Bignum#hash): remove its definition because it is unified
	  with Object#hash.

	* include/ruby/intern.h (rb_big_hash): add a prototype declaration.

	* hash.c (any_hash): treat Bignum values directly.
