Tidy up collab-related signature help data (#14377)
Follow-up of https://github.com/zed-industries/zed/pull/12909

* Fully preserve LSP data when sending it via collab, and only strip it
on the client.
* Avoid extra custom request handlers, and extend multi LSP server query
protocol instead.

lsp: Implement textDocument/signatureHelp for ProjectClientState::Local environment (#12909)
Closes https://github.com/zed-industries/zed/issues/5155
Closes https://github.com/zed-industries/zed/issues/4879


# Purpose
There was no way to know what to put in function signatures or struct
fields other than hovering at the moment. Therefore, it was necessary to
implement LSP's `textDocument/signatureHelp`.

I tried my best to match the surrounding coding style, but since this is
my first contribution, I believe there are various aspects that may be
lacking. I would greatly appreciate your code review.

# Description
When the window is displayed, the current argument or field at the
cursor's position is automatically bolded. If the cursor moves and there
is nothing to display, the window closes automatically.
To minimize changes and reduce the burden of review and debugging, the
SignatureHelp feature is implemented only when `is_local` is `true`.
Some `unimplemented!()` macros are embedded, but rest assured that they
are not called in this implementation.

# How to try it out
Press `cmd + i` (MacOS), `ctrl + i` (Linux).

# Enable auto signature help (2 ways)
### Add `"auto_signature_help": true` to `settings.json`

Or

### Press `Auto Signature Help`. (Default `false`)

# Disable to show signature help after completion
### Add `"show_signature_help_after_completion": false` to
`settings.json`
