Fixed #27731 -- Implemented CreateModel/AlterFooOperation reduction.
...
This should alleviate the side effects of disabling the AlterFooOperation
reduction with RemoveField to fix refs #28862 during migration squashing
because CreateModel can perform a reduction with RemoveField.
Thanks Nick Pope for the review.

Fixed #28862 -- Disabled optimization of AlterFooTogether and RemoveField.
...
AlterFooTogether operations cannot be swapped with RemoveField operations on
the same model as they could be removing the the same field as well.
Since AlterFooTogether operations don't track what their previous value was,
it's impossible to determine whether or not the optimization is safe so the
only way to proceed is to disable the optimization.
Thanks Ramiro Morales for the in-depth analysis of the issue.

Refs #27768 -- Reversed order of optimized and in-between operations.
...
Operations can only be optimized through if they don't reference any of the
state the operation they are compared against defines or alters, so it's
safe to reverse the order.
