Generating SaticMethods protocol ignores 'static native' java methods

[ktoso]

// JNIExample.java

package com.example;

public class JNIExample {
    static {
        System.loadLibrary("my-swift-lib");
    }

    public native int compute(int a, int b);
    public native int compute(int a, Integer b);

    public static native int computeStatic(int a, int b);

    public static void main(String[] args) {
        int result = new JNIExample().compute(5, 7);
        System.out.println("Result from native code: " + result);
    }
}

will generate the sayHello and compute but will ignore the computeStatic:

/Users/ktoso/code/swift-java/Samples/JavaKitSampleApp/.build/arm64-apple-macosx/debug/Java2Swift-tool --module-name SwiftJNIExample --depends-on JavaKit=/Users/ktoso/code/swift-java/Sources/JavaKit/swift-java.config --swift-native-implementation com.example.JNIExample $(pwd)/swift-java.config

@JavaClass("com.example.JNIExample")
open class JNIExample: JavaObject {
  @JavaMethod
  @_nonoverride public convenience init(environment: JNIEnvironment? = nil)
}
extension JavaClass<JNIExample> {
  @JavaStaticMethod
  public func main(_ arg0: [String])
}
/// Describes the Java `native` methods for ``JNIExample``.
///
/// To implement all of the `native` methods for JNIExample in Swift,
/// extend JNIExample to conform to this protocol and mark
/// each implementation of the protocol requirement with
/// `@JavaMethod`.
protocol JNIExampleNativeMethods {
  func compute(_ arg0: Int32, _ arg1: JavaInteger?) -> Int32

  func compute(_ arg0: Int32, _ arg1: Int32) -> Int32
}

We need to be able to handle static native methods as well.
