[cli] refine debug command list for better diagnostic output (#12799)

Removed redundant channel, panid, and extpanid commands. Their
information is now more comprehensively provided by the dataset active
-ns output.

Removed partitionid from the debug command list as it was redundant
with leaderdata.
