重载
GetCompletionContextAsync(InitialTrigger, SnapshotPoint, SnapshotSpan, CancellationToken)
每次完成会话时调用一次，以获取给定位置上所有可用完成项的集合。 在后台线程上调用。

- trigger
- InitialTrigger
导致完成的原因
- triggerLocation
- SnapshotPoint
在与此内容类型匹配的主题缓冲区上触发了完成的位置 IAsyncCompletionSource
- applicableToSpan
- SnapshotSpan
完成将在视图的数据缓冲区中发生的位置： TextBuffer
- token
- CancellationToken
可能中断此操作的取消标记
