Classes made from Struct should have default `new` singleton method.
[Bug #16465] [Bug #16801]
[Fix GH-2795] [Fix GH-2944] [Fix GH-3045] [Fix GH-3093]
Note: Backporting shouldn't modify object.h and instead can use
struct_new_kw which is basically a duplicate implementation of
rb_class_new_instance_pass_kw
