Merge branch 'veristat: replay, filtering, sorting'

Andrii Nakryiko says:

====================

This patch set adds a bunch of new featurs and improvements that were sorely
missing during recent active use of veristat to develop BPF verifier precision
changes. Individual patches provide justification, explanation and often
examples showing how new capabilities can be used.
