JENA-2345: Better report message for DatatypeConstraint

> DatatypeConstraint could produce missleading message
> ----------------------------------------------------
>
>                 Key: JENA-2345
>                 URL: https://issues.apache.org/jira/browse/JENA-2345
>             Project: Apache Jena
>          Issue Type: Bug
>          Components: SHACL, ShEx
>    Affects Versions: Jena 4.5.0
>            Reporter: Jakub Wach
>            Priority: Minor
>         Attachments: DatatypeConstraint.patch
>
>
> Description:
>  * SHACL implementation class DatatypeConstraint could return misleading 
> message when datatype of the literal node does violates the shape. e.g:
>  ** `{color:#6a8759}Got datatype xs:int : Node 
> {color}{color:#cc7832}\"{color}{color:#6a8759}strValue2{color}{color:#cc7832}\"{color}`
>  ** Current implementation does either quote expected datatype or actual 
> datatype of the node. It all depends on prefix mapping! 
>  * Shape/constraint: https://www.w3.org/TR/shacl/#DatatypeConstraintComponent
> Possible solutions: 
>  * Always use expected data type:
>  ** Possible messages:
>  *** {color:#6a8759}`Expected datatype xs:int : Node 
> {color}{color:#cc7832}\"{color}{color:#6a8759}strValue2{color}{color:#cc7832}\"{color}`,
>   
>  *** {color:#6a8759}`Expected datatype <http://......./....> : Node 
> {color}{color:#cc7832}\"{color}{color:#6a8759}strValue2{color}{color:#cc7832}\"{color}`
>  ** Keeps possibility to use prefix
>  ** Somewhat consistent with ClassConstraint
>  ** Possible patch in attachments (not tested!).
>  * Alternatively message could be similar to SHEX equivalent.
