Improve support for Java varargs methods

Java supports varargs methods. For example, [Class.getMethod](https://developer.android.com/reference/java/lang/Class.html#getMethod%28java.lang.String, java.lang.Class<?>...%29)

Method getMethod (String name, Class...<?> parameterTypes)

This is syntax sugar for the actual method signature which is

Method getMethod (String name, Class<?>[] parameterTypes)

Currently, NativeScript for Android does not support calling such method with implicit parameter

var klass = java.lang.Object.class;

// option 1) not supported
var method = klass.getMethod("hasCode");

// option 2) supported
var method = klass.getMethod("hasCode", null);

We can provide another implementation for the current method resolution algorithm so it tries to find a method with one additional parameter (array) as a fallback and if this fail then the method resolution fails as expected.

从 NativeScript Android runtime 中当前的方法解析算法开始，跟踪 JavaScript 调用如何与 Java 方法匹配。根据 issue 中隐式和显式 varargs 的示例验证行为。完成的标准是：省略的 varargs 参数通过数组参数回退得到解析，而无法解析的方法仍然按正常情况失败。
