RANAP: Split FormatInformationParameter / SDUParameterItem

The definition of the above data types as per 3GPP specs results in a
SEQUENCE_OF() an anonymous structure, which is slightly inconvenient to
use.  So let's split the SEQUENCE OF part and the actual definition of
the item in separate types.
