Split GTP_CodecPort/GTP_Templates into C and U variants 

The Types are already split in the dependent modules in GTPC_Types and
GTPU_Types.
There's no point in keeping them together in the same file since those 2
protocols are mostly independent.
Furthermore, testsuites using GTPv2C + GTPv1U don't need GTPv1C.
