RFR: 8273339: IOOBE with ListChangeListener added to the selectedItems list of a TableView

Fri Jan 7 20:05:46 UTC 2022

This PR converts the change's `from` field from a list of tablePositions into a list of selected indices of rows.

It includes two tests for TableView and one for TreeTableView (the second test wasn't included due to an [issue|https://bugs.openjdk.java.net/browse/JDK-8232825] with key navigation), that pass with this PR and fail without it.
