Multiple issues fixed here that prevent building Wasm Swift SDK on macOS: 1. After bumping WASI-libc to `wasi-sdk-31` tag, while building `compiler-rt`, `CMAKE_C_COMPILER_TARGET` is not set correctly, and `CMAKE_C_COMPILER_WORKS` should skip failing checks. 2. When building Swift SDKs, passing `SWIFT_WASI_SYSROOT_PATH` excludes `wasm32-unknown-none-wasm` Embedded Swift triple from building, which makes it hard to experiment with Wasm features like components that shouldn't have dependencies on `wasip1` ABI. 3. Now with `wasm32-unknown-none-wasm` triple present, `test/embedded/wasm/classes.swift` can pass, but it needs `test-resource-dir`. rdar://173926794
