d_a_obj_kwheel00, 01, & d_a_obj_klift00 Equivalent (weak func and/or vtable order) (#2291)

* d_a_obj_kwheel00, 01, & d_a_obj_klift00 Equivalent (weak func and/or vtable order)
* Three rels equivalent
* Basic documentation for the three rels
* Define explicit constructor for dMdl_obj_c (needed for proper array creation in d_a_obj_klift00)
* Modify d_a_obj_bky_rock to account for new explicit constructor of dMdl_obj_c
* Specify weak func and/or vtable orders for rels in config.py

* Cleanup includes and dol2asm artifacts

* * Fix debug build
* Restore incorrectly removed l_bmdidx

* Fix US retail equivalency
