Subject: [PATCH] meson: wrap html documentation generation with gtk_doc option

By default, if a host environment has the `rst2html5` application
available, builds will automatically perform some HTML documentation
generation from the documentation's glib reference content (e.g.
creating `gvariant-specification-1.0.html`). The creation of this
documentation is not required for all use cases.

This commit tweaks the building of the HTML-based GLIB specification
document to be guarded by `gtk_doc`.
