ClassCleanupManager.MarkTestComplete is inefficient

Create a test class with a parameterized test that has a million test case. Profile it to see:

21 sec (45% of CPU time) is spent just in List<T>.Remove

[nohwnd]

does this scale down to 1000-10000 data rows? OR to 1000-10000 tests? Did you see anyone having actual test with 1milion data rows?

Unlikely 😄

I will probably try to get the average and maximum number of tests in a single class from dotnet/roslyn.

I usually tested on 10, 100 and 1000 and 10k items, to see if that performance is mostly linear. And if it was it was good enough.
