[lexical] Feature: Add onUpdate function during update with $onUpdate (correct baselline)

[landisdesign]

Description

Adds $onUpdate(fn) to allow an in-progress update/command to append a function to the _deferred stack.

Closes #6767

Test plan

Before

This functionality did not exist. Calling editor.update with an onUpdate function was the only way to perform an action after an update.

After

Performing an update such as:

editor.update(() => {
  // perform updates
  $onUpdate(() => {
    console.log('second onUpdate);
  });
}, {
  onUpdate: () => {
    console.log('first onUpdate');
  }
});

would emit first onUpdate, followed by second onUpdate, once the updates were flushed. This is essentially what the unit test does.

Looks good to me! I think the only thing missing here is a flow definition
