gstreamer: meta: Move has_tag() and tags() getters to MetaRef

Browse source 
On `MetaAPI` only the static meta API type is known and based on that
it's not possible to work with the tags of a specific meta instance's
API.

As the methods take a `&self` anyway they would be expected to check the
value at hand instead.
