Existing EAP-AKA and EAP-SIM dissector is missing AT_NONCE_MT, AT_VERSION_LIST,
AT_SELECTED_VERSION, AT_BIDDING, AT_IPMS_IND, AT_IPMS_RES and AT_TRUST_IND
attribute definitions.

I added those new definitions in existing value_string array. 


Both EAP methods are using same "IANA number space"
(http://www.iana.org/assignments/eapsimaka-numbers/eapsimaka-numbers.xml). Both
are closely related with most of attributes being shared between them and ones
that are not being shared being explicitly reserved for same functionality in
other's RFC (e.g. AT_VERSION_LIST is referenced from EAP-AKA specification
although it is currently only used in EAP-SIM).

That is why I also refactored code by extracting their definitions from
function level and adjusting val_to_str conversion accordingly.
