Windows: bring back tests disabled by #13133 (#13711)

PR #13133 disabled various tests as they failed or flaked when compiled
with clang-cl. Given we have some significant other blockers to adding
clang-cl support and enabling as many tests to run in CI as possible is
important to progress to beta/GA support, we can un-skip these tests.

We could be "clever" and use a select to only tag tests to be skipped
when built with a specific compiler and compilation mode as well as an
alternative.
