RFR: 8089280: horizontal scrollbar should never become visible in TableView with constrained resize policy [v4]

[Andy Goryachev]

> Modified the tree/table view internals to suppress the horizontal (a.k.a. breadth in VirtualFlow) scroll bar when a constrained resize mode is in effect.  This change complements fixes added in [JDK-8089009](https://bugs.openjdk.org/browse/JDK-8089009) without addressing other bugs found in https://bugs.openjdk.org/browse/JDK-8292810
