Provide standard infrastructure for clearing global caches #102080
Description
It turns out that some global caches have memory leak issues while the refleak CI is running.
The global cache is not the problem, but we must provide a better solution to clear them after the tests.
Suggestion from @gvanrossum: #101988 (review)

Look hard, I think there is test infra code that handles a bunch of these. @JelleZijlstra ?

I know this cache-related helper:
cpython/Lib/test/libregrtest/utils.py
Line 116 in ed01add

Thanks Nikita, I was just looking for that too.
I'm not sure we need any other general mechanism. If there's anything missing from
libregrtest.utils.clear_caches, we should simply add it.gvanrossum commentedon Feb 20, 2023
That's the one I remembered.

Looks like #101988 should be ported to use
libregrtest.utils.clear_cachesI will submit the patch soon.
