Add a new decorator `skipIfTargetDoesNotSupportThreads` to skip tests that use threading. This is motivated by running the test suite targeting WebAssembly, where `wasip1` does not support threads. There are variants that do support threading (e.g. `wasip1-threading`) that the current implementation accounts for.
