[FAB-12606] Remove unnecessary CC Type check

It is not actually necessary to specify the
CC type when instantiating chaincode as
CC name and version are actually used to
get the installed chaincode bytes from the
filesytem.

With this change, CCType is no longer checked
at all during instantiate and is therefore no
longer required (which will make things easier
for clients)
