 rts: Rip out support for STM invariants

 This feature has some very serious correctness issues (#14310),
 introduces a great deal of complexity, and hasn't seen wide usage.
 Consequently we are removing it, as proposed in Proposal #77 [1]. This
 is heavily based on a patch from fryguybob.

 Updates stm submodule.
