Revise skipped tests with pypy on windows after bumping pypy

[xrmx]

Is your feature request related to a problem?

We have some tests that are skipped on Windows and Pypy, revise after we bump our baseline to 3.9 and so we can bump the pypy version.

There were changes around timer precision on 7.3.12 that maybe will help: https://doc.pypy.org/en/latest/release-v7.3.12.html#id2

Describe the solution you'd like

Drop the skipif after bumping pypy.

Describe alternatives you've considered
