editor: Add Organize Imports Action (#25793)

Closes #10004

This PR adds support for the organize imports action. Previously, you
had to manually configure it in the settings and then use format to run
it.

Note: Default key binding will be `alt-shift-o` which is similar to
VSCode's organize import. Also, because `cmd-shift-o` is taken by
outline picker.

Todo:

- [x] Initial working
- [x] Handle remote
- [x] Handle multi buffer
- [x] Can we make it generic for executing any code action?

Release Notes:

- Added `editor:OrganizeImports` action to organize imports (sort,
remove unused, etc) for supported LSPs. You can trigger it by using the
`alt-shift-o` key binding.
