Run organise imports on save

[jrieken]

re #46589

It should be possible to configure organise import (read code actions in general) so that they run on save.

Yes, currently the feature is not reliable enough for me to feel confident triggering it on save but next iteration we should hook this up

Depends on #42092

A better option imho would be to make it configurable to be run when formatting, rather than on save. At least I would expect auto format to handle such things, rather a file save...

Enabled by #48086,

	"editor.codeActionsOnSave": {
		"source.organizeImports": true
	}

This is not enable by default currently
