Search libgdiplus in macports install location (#47373)

When `libgdiplus` is installed via macports, `System.TypeInitializationException` exception is thrown. This is because macports installs the library in `/opt/local/lib`. ```sh $ port install libgdiplus $ port contents libgdiplus Port libgdiplus contains: /opt/local/lib/libgdiplus.0.dylib /opt/local/lib/libgdiplus.a /opt/local/lib/libgdiplus.dylib /opt/local/lib/pkgconfig/libgdiplus.pc /opt/local/share/doc/libgdiplus/AUTHORS /opt/local/share/doc/libgdiplus/COPYING /opt/local/share/doc/libgdiplus/ChangeLog /opt/local/share/doc/libgdiplus/LICENSE /opt/local/share/doc/libgdiplus/NEWS /opt/local/share/doc/libgdiplus/README.md /opt/local/share/doc/libgdiplus/TODO ``` PR adds `/opt/local/lib/libgdiplus.dylib` as a well-known probing path.
