Create a testing-only handshake for shaking the bugs out of wide create cells (prop249)

We need a handshake that doesn't fit in a single CREATE cell so that we can make sure that prop249 is implemented properly.

My current recommendation is "nnttoorr", which is the same as ntor, but every byte is repeated twice. ;)

Assigning the crazypants handshake to myself, since I'll need to touch this part of the codebase (or at least become super familiar with it) for #24988 (moved).

Also, depending on timing of when things are finished, it might be possible to use the work from #24987 (moved) (since it composes two handshakes by taking function pointers to the implementations) to chain ntor+ntor to accomplish this task… that would involve no (or very little) new code.

We won't get PQ or wide-create done in this release. :/
