Support VM version 8.3.0

[annagrin]

The version adds an optional parameter libraryFilters to the getSourceReport VM service API.

@override
  Future<SourceReport> getSourceReport(
    String isolateId,
    /*List<SourceReportKind>*/ List<String> reports, {
    String? scriptId,
    int? tokenPos,
    int? endTokenPos,
    bool? forceCompile,
    bool? reportLines,
    List<String>? libraryFilters,
  }) ```

The libraryFilters parameter is intended to be used when gathering coverage for the whole isolate. If it is provided, the SourceReport will only contain results from scripts with URIs that start with one of the filter strings. For example, pass ["package:foo/"] to only include scripts from the foo package.
