	Fix frozen status loss when moving objects

	[Bug #19536]

	When objects are moved between size pools, their frozen status is lost
	in the shape. This will cause the frozen check to be bypassed when there
	is an inline cache. For example, the following script should raise a
	FrozenError, but doesn't on Ruby 3.2 and master.

	    class A
	      def add_ivars
	        @a = @b = @c = @d = 1
	      end

	      def set_a
	        @a = 10
	      end
	    end

	    a = A.new
	    a.add_ivars
	    a.freeze

	    b = A.new
	    b.add_ivars
	    b.set_a # Set the inline cache in set_a

	    GC.verify_compaction_references(expand_heap: true, toward: :empty)

	    a.set_a
