David Peter 642eac452d [ty] Recursive protocols (#17929) ...

## Summary

Use a self-reference "marker" ~~and fixpoint iteration~~ to solve the
stack overflow problems with recursive protocols. This is not pretty and
somewhat tedious, but seems to work fine. Much better than all my
fixpoint-iteration attempts anyway.

## Test Plan

New Markdown tests.
