Follow-up of https://github.com/zed-industries/zed/pull/35306
This PR contains two changes:
Both changes are inspired from:
d90a87f955/client/src/common/textSynchronization.ts
1. Handling `textDocument/didSave` and `textDocument/didChange`
registration and unregistration correctly:
```rs
#[derive(Debug, Eq, PartialEq, Clone, Deserialize, Serialize)]
#[serde(untagged)]
pub enum TextDocumentSyncCapability {
Kind(TextDocumentSyncKind),
Options(TextDocumentSyncOptions),
}
```
- `textDocument/didSave` dynamic registration contains "includeText"
- `textDocument/didChange` dynamic registration contains "syncKind"
While storing this to Language Server, we use
`TextDocumentSyncCapability::Options` instead of
`TextDocumentSyncCapability::Kind` since it also include
[change](be7336e92a/src/lib.rs (L1714-L1717))
field as `TextDocumentSyncCapability::Kind` as well as
[save](be7336e92a/src/lib.rs (L1727-L1729))
field as `TextDocumentSyncSaveOptions`. This way while registering or
unregistering both of them, we don't accidentaly mess with other data.
So, if at intialization we end up getting
`TextDocumentSyncCapability::Kind` and we receive any above kind of
dynamic registration, we change `TextDocumentSyncCapability::Kind` to
`TextDocumentSyncCapability::Options` so we can store more data anyway.
2. Modify `include_text` method to only depend on
`TextDocumentSyncSaveOptions`, instead of depending on
`TextDocumentSyncKind`. Idea behind this is,
`TextDocumentSyncSaveOptions` should be responsible for
"textDocument/didSave" notification, and `TextDocumentSyncKind` should
be responsible for "textDocument/didChange", which it already is:
