Allow Untitled documents that do not require save dialog when closing

[sandipchitale]

Extensions may generate some content and show it in Untitled document with a specific language id so that syntax coloring and other possible language-specific features are activated. For example, the Helm extras loads Manifests, Templates, Values, Hooks, or Notes from a Helm release. It sets the correct language id for these Untitled documents. However, these documents are just previews, and as such users should not be required to save these preview documents. If they simply want to close the documents they should not encounter the Save dialog. Of course, they can click on Don't Save, but that is a hiccup. This hiccup also happens when closing the VSCode window. I guess this could be done by clearing the dirty flag of the editor/document. For security reasons, only the creating extension should be allowed to do so. Or this could be a flag while creating the document in the first place via vscode.workspace.openTextDocument 's options parameter. For example:

options?: { language?: string; content?: string; saveNotRequired?: boolean;}

I have seen some extensions use TextDocumentContentProvider, but that is too heavy and does not work well when the content is already available.

Just came across this: #154457

Not sure how it relates and whether the handler will be available to extension authors?

@riccardoferretti I guess this is a special case of #154457. My request is to let untitled editors not require any Save/Discard/Cancel Dialog hiccup, under the control of the extension which creates the editor with pre-created content. Of course Save As, Pinning, etc should still be possible.
