[WebAssembly] Move getLibcallSignature into WebAssembly namespace (NFC) (#85171)

These are Wasm only functions so they are better be within `WebAssembly`
namespace rather than the `llvm` namespace which includes the whole
LLVM.

Also this removes `extern` keywords which are not strictly necessary.
