Michael Anthony Knyszek 3f002abb60 internal/sync: add test from issue 70970
This test checks a use-case of sync.Map that's expected to be more
common in Go 1.24 and beyond, as a concurrent weak cache.

The test will also fail if CompareAndSwap is not properly atomic with
CompareAndDelete, which is what #70970 is actually about. We should have
more explicit tests checking mutual atomicity of operations, but
for now this is OK, and still useful.

For #70970.
