SHACLC: support SPARQL

### Version

5.2.0

### Feature

Get https://github.com/Sveino/Inst4CIM-KG/tree/develop/source/CGMES/v3.0/SHACL/ttl (these are complex electrical CIM/CGMES shapes).

Try `shacl.bat -out=c` on two of the files and you get these messages:
- "sh:target not supported in compact syntax" (happens on `61970-301_Equipment-AP-Con-Complex-SHACL_v3-0-0.ttl`)
- "SparqlConstraint Not supported in compact syntax" (happens on `61970-302_Dynamics-AP-Con-Complex-SHACL_v3-0-0.ttl`, at end of output)

### Are you interested in contributing a solution yourself?

None

Start by reproducing `shacl.bat -out=c` with the two SHACL files named in the issue. Trace how compact syntax handles `sh:target` and `SparqlConstraint`, then verify that both files convert without the reported unsupported messages. A complete change should support these constructs in the compact output.
