Support cipher mode reject with extended cause
* add function to generate cipher mode reject with extended (2-byte) Cause IE * add function to get (extended) Cause value * add corresponding (extended cause) test * update existing (non-extended cause) test * use enum as a parameter for existing non-extended version to make interface more unified Change-Id: Id5509b94a18180a44f45300caaa02b843c166fa3 Related: OS#3187
