Outline view should indicate access modifiers

Type: Feature Request

I would like the Outline view to display an icon marker showing whether a method is private/public/protected, static or not, final or not, synchronized or not, etc. Generally when looking at a class outline, I want to quickly see which methods are public and which aren't.

该 issue 没有指定文件、测试或入口点。首先定位 vscode-java extension 中的 Java Outline view，并检查符号的呈现方式。完成的标准是：Outline view 能够在视觉上区分 public、private 和 protected 方法，并且已明确所请求的其他修饰符指示器，并通过测试覆盖。
