Support llmGenerated property on CodeAction

[StellaHuang95]

Addresses #1555

• Added llmGeneratedSupport to CodeActionClientCapabilities.
• Added llmGenerated to CodeAction.
• Added conversion logics in protocolConverter and codeConverter.
• Added the proposed api to the enabledApiProposals in package.json and the corresponding .d.ts file.

Looking at the implementation now another boolean here feels wrong. I think we should follow the same approach as we did with other literals and add a tags field with CodeActionTag (like SymbolTag or CompletionItemTag). This make it homogenous with approaches we use somewhere else.

Great work. Only some minor wording tweaks.

Let's wait until we have the spec right and then we finish up the coding. Is that OK for you?

Sure, I've updated the spec. Let me know if it looks good:)

I've added the tagSupport client capability, let me know if there's anything else. Thanks!

As far as I can tell this is enabled for the extension (in product.json). Marking the extension side verified (microsoft/vscode-python#24068)
