Use editor gutter for (super) implementation navigation

Can an icon be added to the left of the interface declaration and methods for quick jumps to related implementations? ( and an icon for quick jump to related Interface)

example from IntelliJ IDEA:

Environment

• Operating System: Linux
• JDK version: 17
• Visual Studio Code version: 1.87.0
• Java extension version: v1.28.1

Steps To Reproduce

1. Create a java interface
2. Create an implementation of this interface

Current Result

Expected Result

Additional Informations

In Java development, many people are accustomed to using the icons next to Interfaces to jump to the implementations of the interface, or using the related icons inside a Class to jump to the corresponding Interface definition. The support for this feature in vscode-java can facilitate a smoother adaptation to these user habits.

该 issue 没有提供文件、测试或入口点。创建一个 Java 接口及其实现来重现报告的案例，然后跟踪 VS Code Java extension 的导航行为。当接口声明和方法旁边出现 gutter 图标，并且可以跳转到实现以及返回相关接口时，即表示完成。
