[Suggestion] Add ability to define an enum without using a table

How are you using the lua-language-server?

Visual Studio Code Extension (sumneko.lua)

Which OS are you using?

Windows

What is the issue affecting?

Annotations, Type Checking, Completion

Suggestion

For existing codebases where enums are defined like this:

OPERATING_SYSTEM_WINDOWS = 1
OPERATING_SYSTEM_MAC = 2
KEY_A = 1
KEY_B = 2

it would be nice to be able to define all lines that follow (until the next blank line) as part of an enum without changing anything by introducing a table: i.e.

@enum OPERATING_SYSTEM
OPERATING_SYSTEM_WINDOWS = 1
OPERATING_SYSTEM_MAC = 2

@enum KEY
KEY_A = 1
KEY_B = 2

This would be convenient for type annotating when the values are passed as parameters and what-not. I'm not able to find any existing ways to designate these values as a "group" (or union) that maintains their use as global constants.

首先定位处理全局常量的注解、类型检查和补全入口。将提议的 @enum 块与现有注解语法进行比较，并确定枚举成员关系应如何影响参数类型标注，同时保留全局常量的使用方式。完成标准是：连续的常量可以分组到空行为止，并且能被注解、类型检查和补全一致地识别。
