Fixes#22353
StatusBarItem is one of the few places in our API where we only allow extensions to give us a command as a `string` instead of as `Command` object. This change updates the API to also allow passing in a `vscode.Command` (which also allows arguments!)
For #77131
**Motivation**
While our existing webview editor API proposal more or less works, building an editable webview editor is fairly tricky using it! This is especially true for simple text based editors.
It'd also be nice if we could get bi-directional live editing for text files. For example, if I open the same file in a webview editor and in VS Code's normal editor, edits on either side should be reflected in the other. While this can sort of be implemented using the existing API, it has some big limitations
**Overview of changes**
To address these problems, we've decided have two types of webview editors:
- Text based webview editors. These editors used a `TextDocument` as their data model, which considerably simplifies implementing an editable webview. In almost all cases, this should be what you use for text files
- Complex webview editors. This is basically the existing proposed API. This gives extension hooks into all the VS Code events, such as `save`, `undo`, and so on. These should be used for binary files or in very complex text editor cases.
Both editor types now have an explicit model layer based on documents. Text editor use `TextDocument` for this, while custom editors use `WebviewEditorCustomDocument`. This replaces the delegate based approach previously used.
Adds contributable commands to timeline items

- extract a separate DocumentRangeSemanticTokensProvider that deals with a document range
- extract a separate provideDocumentSemanticTokensEdits that deals with updating via SemanticTokensEdits a previous result
* Add common service for logging deprecated api usage
For #88391
Adds a new `ExtHostApiDeprecationService`. This service logs a warning and telemetry when a deprecated API is used.
Updates some of the more simple deprecated apis to use this new service
* Note that extensionId cannot be undefined
* Fix event name
