[Fast Refresh] Make edits to a memo comparison function take effect (#36964)

Editing the second argument of memo() previously never took effect
until something else remounted the tree, for two separate reasons:

- When adding a comparison function, we need to switch from
  SimpleMemoComponent to MemoComponent so canPreserveStateBetween
  should return false.
- MemoComponent was missing from the hot reload type resolution in
  createWorkInProgress, so existing fibers kept reading .compare from
  the old memo object forever.

New behavior:

- Adding or removing the comparison function remounts; we need to do
  this when adding (SimpleMemoComponent doesn't support a comparison
  function) so let's also do it when removing.
- Editing the comparison function implementation applies in place
  with state preserved

The TODO in isCompatibleFamilyForHotReloading is removed as that
wasn't the right place to do this check.
