textDocument/inlineCompletion method

Do you think it could be well placed for blink to support textDocument/inlineCompletion.

This method from the 3.18 spec is used for inline AI style completions from LSPs.

At the moment, the only concrete implementation I know of is:
https://www.npmjs.com/package/@github/copilot-language-server

But this would allow for AI completions from LSP without any additional blink plugins.
Seeing as blink already supports ghost text and a completion engine, all the moving parts appear to be there

There is a issue for this to be supported in core but it may be a good idea for a plugin to support an implementation first

Yeah this looks great, possibly a good candidate for #1059
