[GStreamer] Harness: graph dump support
https://bugs.webkit.org/show_bug.cgi?id=252559
Reviewed by Xabier Rodriguez-Calvar.
In cases where a graph dump of the harness and its downstream harnesses is
needed for debugging
purposes, it can be done by calling the `dumpGraph()` method. At runtime you
need to set the
`$WEBKIT_GST_HARNESS_DUMP_DIR` environment variable to a filesystem directory
path where `mmd`
[Mermaid](https://mermaid.js.org/) files will be created. Those can then be
exported to SVG or
PNG using the mermaid CLI tools or the [live editor](https://mermaid.live).
