Should `vscode.executeInlayHintProvider` gain `itemResolveCount` as an argument?

[DavisVaughan]

API commands like vscode.executeCodeActionProvider and vscode.executeCompletionItemProvider have an itemResolveCount argument:

https://github.com/microsoft/vscode/blob/70107d1562c0c496e4bc8bbe1ba4607ee56261fe/src/vs/workbench/api/common/extHostApiCommands.ts#L271-L277

https://github.com/microsoft/vscode/blob/70107d1562c0c496e4bc8bbe1ba4607ee56261fe/src/vs/workbench/api/common/extHostApiCommands.ts#L308-L315

This is used to do the 2nd half of these LSP language features, where you sometimes need to "resolve" the items in a more expensive way.

I noticed that vscode.executeInlayHintProvider does not have this argument, meaning that the Inlay Hint Resolve bit can't be called in the same way: https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#inlayHint_resolve

https://github.com/microsoft/vscode/blob/70107d1562c0c496e4bc8bbe1ba4607ee56261fe/src/vs/workbench/api/common/extHostApiCommands.ts#L364-L370

Would it make sense to add itemResolveCount to vscode.executeInlayHintProvider to support this? Or maybe some other hook like vscode.resolveInlayHintProvider?

I assume this might be somewhat hard to do performantly in vscode.executeInlayHintProvider itself, because you probably want to show a lot of inlay hints but only resolve one when the user double clicks on it to retrieve delayed textEdits.
