[media] docs-rst: convert uAPI structs to C domain
instead of declaring the uAPI structs using usual refs, e. g.:
.. _foo-struct:
Use the C domain way:
.. c:type:: foo_struct
This way, the kAPI documentation can use cross-references to
point to the uAPI symbols.
That solves about ~100 undefined warnings like:
WARNING: c:type reference target not found: foo_struct
