merge revision(s) 53382,53511,53512: [Backport #11916]

	fix commit miss

	* test/test_forwardable.rb: add tests for r53381.
	* lib/forwardable.rb: Convert given accessors to String.
	  r53381 changed to accept only Symbol or String for accessors, but
	  there are several rubygems that pass classes (e.g. Array,
	  Hash, ...) as accessors. Prior r53381, it was accepted because Class#to_s
	  returns its class name. After r53381 given accessors are checked
	  with define_method, but it accepts only Symbol or String, otherwise
	  raises TypeError.
	      def_delegator Foo, :some_method
	  This change is to revert unwanted incompatibility. But this behavior
	  may change in the future.
	  This change is to revert unexpected incompatibility. But this behavior
