[Interop] [SwiftToCxx] New Throw Error Test

[Robertorosmaninho]

This PR aims to introduce the known issue of Swift functions that thrown don't be translated as such when creating the bridge header file.

Given this simple function:

public func emptyThrowFunction() throws { print("passEmptyThrowFunction") }

The Expected Signature of emptyThrowFunction():

SWIFT_EXTERN void $s9Functions18emptyThrowFunctionyyKF(void) SWIFT_CALL; // emptyThrowFunction()
...
inline void emptyThrowFunction() {
    return _impl::$s9Functions18emptyThrowFunctionyyKF();
 }

The Current Signature of emptyThrowFunction():

SWIFT_EXTERN void $s9Functions18emptyThrowFunctionyyKF(void) SWIFT_NOEXCEPT SWIFT_CALL; // emptyThrowFunction()
...
inline void emptyThrowFunction() noexcept {
  return _impl::$s9Functions18emptyThrowFunctionyyKF();
}

This test is marked as XFAIL: * since it will fail in any context due to the hardcoded attributes SWIFT_NOEXCEPT and noexcept on the Swift Compiler.
