perf annotate stdio: Support --show-nr-samples option

Browse Source 
Add --show-nr-samples option to "perf annotate" so that it matches "perf
report".

Committer note:

Note that it can't be used together with --show-total-period, which
seems like a silly limitation, that can be lifted at some point.

Made it bail out if not on --stdio.
