Common: LambdaUtils: Add a more general filter by type method.

* The current filterByType methods has fairly strict expectations
  towards inheritance which restricts the use of the method.
* Add a more generic filterType method that has less restrictions
  w.r.t. the generics.
* Rename the existing method to filterTypeSafe.
