gsm_sim: add decoding for GET IDENTITY and GET DATA 

Add support for decoding instruction byte 78 (GET IDENTITY) from
TS 102 221 v15.11.0 and instruction byte CA (GET DATA) which is used to
retrieve the EID for eSIMs according to GSMA SGP.02 v4.2 available from
https://www.gsma.com/esim/esim-m2m-specifications/.

Closes #17548.
