Subject: [PATCH] meson: error out if introspection is enabled but gobject
 isn't

In case a user passed -Dintrospection=enabled the build would just ignore
it by default because gobject defaults to disabled and the introspection build
gets skipped.

Instead, if introspection is explicitly enabled but gobject is for some reason
missing error out.

Fixes #2404
