mncc_mt_loadgen.py: add codec arg

Add codec parameter to start_call() and convenience functions mt_call()
and calls() with FR as default. While at it, update the help text.

Duplicate enum codec_type into mncc_mt_loadgen.py, because the enum
values are different from the existing enum values in the python code
(GSM48_BCAP_SV_EFR etc.).
