[wasm] Figure out a way to detect wasm+windows+aot for tests

[radical]

#59479 enables AOT tests on windows, and needs to disable some tests. But we need to be able to detect WASM/Browser+Windows-host case, and surface to PlatformDetection.

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.
