pkg/report: tail reports coming from different executors may be merged

[tarasmadan]

Describe the bug
Extracting the tail reports we don't check whether they belong to the same executor.
+1 to @dvyukov for it.

Cointext - see #6271

[tarasmadan]

What we need is only the output from T12081.

The "thread local" reports are much more valuable than other.
But at the same time, these "indirect reports" also look valuable.
If some WARN is triggering the KASAN signals system wide, it is also the signal. Especially if the KASAN signal is high (>50% for example).

What do you think about storing them in the DB as "direct tail reports" and "indirect tail reports".
By default we'll show only the direct tail reports. Access to the indirect ones will be optional and protected by some flag.
I'd like to check the statistics for direct and indirect in some time.

@ramosian-glider @melver @dvyukov @a-nogikh wdyt?

Context - #6271 . I used all the system wide signals coming from different oracles. And @dvyukov noticed these reports may be coming from the out-of-scope sources.

[melver]

I think this is helpful. I think you could also display a counter like e.g. a "taint score", and count the system-wide reports that are not found any other way, that happened after the initial report.

Before going all way productionazing the changes, changing the database scheme permanently, creating web UI for this, I would prototype the change in syz-manager. A local weekend run on a beefy machine should generate enough data to prove or disprove "look valuable" hypothesis. If I would find >1 actionable items in the local run, I would considering productionazing this. But if the hypothesis is wrong, it may save lots of time and complexity in the syzbot DB/UI.
