tmf: Use basic comparators in TmfSimpleTableViewer

- Make the method createColumn() public and remove createColumns()
  so that the class can be using without needing to be extended.

- Remove ViewerCompoundComparator. We can use basic
  java.util.Comparator's in the analysis and the view, all the
  way until we convert them to ViewerComparator's to pass to the
  TableViewer object.
  This will allow us to re-use comparators defined in the core
  plugin. Chaining of multiple comparators can be done using
  Guava's Ordering.compound() method.

- Support DeferredContentProvider which must be supplied with the
  sort order and ignores the sorter set on the table viewer.
  Remove the method sortOrderChanged().
