### ✅ Viability Checklist

- [x] This wouldn't be a breaking change in existing TypeScript/JavaScript code
- [x] This wouldn't change the runtime behavior of existing JavaScript code
- [x] This could be implemented without emitting different JS based on the types of the expressions
- [x] This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, new syntax sugar for JS, etc.)
- [x] This isn't a request to add a new utility type: https://github.com/microsoft/TypeScript/wiki/No-New-Utility-Types
- [x] This feature would agree with the rest of our Design Goals: https://github.com/Microsoft/TypeScript/wiki/TypeScript-Design-Goals

### ⭐ Suggestion

Take all projects that references a file into consideration when doing goto definition.

### 📃 Motivating Example

Currently when you are working on shared code that calls or uses code that differs in implementation on the client and server the accuracy of goto definition is not optimal. It will just goto either the client or the server. It would be optimal if all relevant definitions were returned.

### 💻 Use Cases

Example project:
```ts
// shared/shared.ts
let x: Thing; // < goto definition here

// project1/tsconfig.json
...

// project1/thingA.ts
interface Thing { a: string }

// project2/tsconfig.json
...

// project2/thingB.ts
interface Thing { b: number }
```

Currently this is returned (depending on order of project load):
```ts
interface Thing { a: string }
```

What ideally should be returned:
```ts
interface Thing { a: string }
interface Thing { b: number }
```

该 issue 指向 tsserver 对多项目 goto-definition 的处理；首先跟踪引用共享文件的项目是如何被选择的。将当前的单一定义结果与示例中预期的定义进行比较，然后建立对返回所有相关结果的覆盖。未指定具体的文件或测试，因此定位实现和测试区域需要熟悉项目。
