Port more tests to the Scheduler.unstable_yieldValue pattern and drop internal.js (#18549)

* Drop the .internal.js suffix on some files that don't need it anymore

* Port some ops patterns to scheduler yield

* Fix triangle test to avoid side-effects in constructor

* Move replaying of setState updaters until after the effect

Otherwise any warnings get silenced if they're deduped.

* Drop .internal.js in more files

* Don't check propTypes on a simple memo component unless it's lazy

Comparing the elementType doesn't work for this because it will never be
the same for a simple element.

This caused us to double validate these. This was covered up because in
internal tests this was deduped since they shared the prop types cache
but since we now inline it, it doesn't get deduped.
