perf annotate browser: Support --show-nr-samples option
Support the --show-nr-samples in the TUI browser.
Committer notes:
Lift the restriction about --tui but leave it for --gtk:
$ export LD_LIBRARY_PATH=~/lib64
$ perf annotate --gtk --show-nr-samples --show-nr-samples is not available in --gtk mode at this time
$
