Auto-complete for table keys with @type breaks on non-locals

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?

Completion

Expected Behaviour

Using ---@type table<KeyType, ValueType> on a table should always keep auto-complete available for keys within the table.

Actual Behaviour

Auto-complete breaks if the table that ---@type was used on is global or within a class.

Reproduction steps

Scenario where auto-complete works:

---@class MyClass
---@field MyThings any

---@type table<string, MyClass>
local SomeTable = {
    SomeKey = {MyField = 1},
    SomeKey2 = {MyField = 1},
}

Scenario where auto-complete does not work:

---@class MyClass
---@field MyThings any

---@type table<string, MyClass>
SomeTable = {
    SomeKey = {MyField = 1},
    SomeKey2 = {MyField = 1},
}

No auto-complete will be available for SomeTable there. This also occurs if SomeTable is within a table marked with ---@class.

在 Visual Studio Code extension 中重现两个表键补全场景，比较使用 table<KeyType, ValueType> 注解的局部表、全局表和类内表。跟踪这些注解的补全处理，并验证在每个场景中键补全仍然可用。
