perf tools: Add pid/tid filtering to report and script commands

The 'record' and 'top' tools already allow a user to specify a CSV of
pids and/or tids of tasks to collect data.

Add those options to the 'report' and 'script' analysis commands to only
consider samples related to the given pids/tids.

This is also inline with the existing comm option.
