atds: add AT&T Device Service implementation

See https://code.wireshark.org/review/gitweb?p=wireshark.git;a=blob;f=epan/dissectors/packet-mbim.c

ATDS/Operators seems to be the same as BasicConnect/VisibleProviders except that
CellularClass has been replaced with a "Provider PLMN Mode".

ATDS/RegisterState seems to be exactly the same as BasicConnect/RegisterState if
the Wireshark dissector is to be believed.

Doesn't implement ATDS/SetProjectionTables yet.
