Tobias Bosch d24df799d3 Revert "feat(iterable_differ): support immutable lists"
In Dart, ImmutableLists are just a projection of an underlying list.
I.e. if the underlying list changes, the ImmutableList also changes.
So we can't make optimizations based on checking whether a collection
is an ImmutableList.

This reverts commit a10c02cb4107624b58b4b3f54da6bf0e0e70c6c6.
