[PATCH 11/16] diagnostics: SARIF output: add "workingDirectory" property (§3.20.19)

[David Malcolm]

gcc/ChangeLog:
        * diagnostic-format-sarif.cc
        (sarif_builder::make_artifact_location_object): Make public.
        (sarif_invocation::sarif_invocation): Add param "builder".
        Use it to potentially populate the "workingDirectory" property
        with the result of pwd (§3.20.19).
        (sarif_builder::sarif_builder): Pass *this to m_invocation_obj's
        ctor.

gcc/testsuite/ChangeLog:
        * c-c++-common/diagnostic-format-sarif-file-1.c: Verify that we have
        a "workingDirectory" property.
