Currently, when building packages for WASI with Embedded Swift, libraries such as `libswift_Concurrency.a` and `libswift_ConcurrencyDefaultExecutor.a` are not discoverable and require passing `-Xlinker <swift-sdk-path>/usr/lib/swift/embedded/wasm32-unknown-wasip1` option manually. This path can be inferred by the driver, which simplifies build invocations for users significantly, while the rest of linkage options (`-lswift_Concurrency` etc) can be specified in toolset files.

Cherry-pick of #1863.
Explanation: Currently, when building packages for WASI with Embedded Swift, libraries such as
libswift_Concurrency.aandlibswift_ConcurrencyDefaultExecutor.aare not discoverable and require passing-Xlinker <swift-sdk-path>/usr/lib/swift/embedded/wasm32-unknown-wasip1option manually. This path can be inferred by the driver, which simplifies build invocations for users significantly, while the rest of linkage options (-lswift_Concurrencyetc) can be specified in toolset files.Scope: Limited to Embedded Swift for Wasm.
Risk: Low due to limited scope.
Testing: Added new automated test cases.
