perf list: Add a --no-desc flag

Browse Source 
Add a --no-desc flag to 'perf list' to not print the event descriptions
that were earlier added for JSON events. This may be useful to get a
less crowded listing.

It's still default to print descriptions as that is the more useful
default for most users.
