RFR: 8089280: horizontal scrollbar should never become visible in TableView with constrained resize policy [v2]

[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
> 
> This PR might need a CSR since a public method is added to VirtualFlow:
> 
> 
>     /**
>      * Suppresses the breadth bar from appearing.
>      */
>     public void setSuppressBreadthBar(boolean suppress) {
>         this.suppressBreadthBar = suppress;
>     }
