Am I correct to assume that I'll need to add similar skip conditions if I enable tests on WinASan and/or clang-cl builds?

Yes, I had inquired about how to set up 'skip-if: compiler != "msvc"' but didn't get a response; it didn't seem to be needed right now, but that's probably the best option...

We don't currently have anything like that, presumably nobody has needed it to this point. Most of the keys used in expressions in test manifests come from the mozinfo.py in mozbuild:
https://dxr.mozilla.org/mozilla-central/source/python/mozbuild/mozbuild/mozinfo.py

It wouldn't be hard to set a 'compiler' key to substs['CC_TYPE'] or something like that.
