gh-158294: Avoid relying on SystemTap probe handler ordering

[stratakis]

Merge the tracing state and filter output in a single probe handler as SystemTap does not guarantee the execution order of handlers sharing a probe point.

• Issue: test_dtrace fails on s390x Fedora buildbots #158294

The six builders that failed in #158294 now pass here:

• https://buildbot.python.org/#/builders/1634/builds/580
• https://buildbot.python.org/#/builders/1666/builds/580
• https://buildbot.python.org/#/builders/1643/builds/581
• https://buildbot.python.org/#/builders/1640/builds/583
• https://buildbot.python.org/#/builders/1652/builds/584
• https://buildbot.python.org/#/builders/1630/builds/675

The "buildbot/AMD64 Windows PGO NoGIL PR" failure is unrelated:

• https://buildbot.python.org/#/builders/1623/builds/494

Backport needed at least for 3.15 where this is failing (for example, https://buildbot.python.org/#/builders/2016/builds/413).
