This fixes#8992 and solves a problem that ESLint/Prettier/... users
have been running into:
They want to format _only_ with ESLint, which is *not* a primary
language server (so `formatter: language server` does not help) and it
is not a formatter.
What they want to use is what they get when they have configured
something like this:
```json
{
"languages": {
"JavaScript": {
"code_actions_on_format": {
"source.fixAll.eslint": true
}
}
}
}
```
BUT they don't want to run the formatter.
So what this PR does is to add a new formatter type: `code_actions`.
With that, users can only use code actions to format:
```json
{
"languages": {
"JavaScript": {
"formatter": {
"code_actions": {
"source.fixAll.eslint": true
}
}
}
}
}
```
This means that when formatting (via `editor: format` or on-save) only
the code actions that are specified are being executed, no formatter.
Release Notes:
- Added a new `formatter`/`format_on_save` option: `code_actions`. When
configured, this uses language server code actions to format a buffer.
This can be used if one wants to, for example, format a buffer with
ESLint and *not* run prettier or another formatter afterwards. Example
configuration: `{"languages": {"JavaScript": {"formatter":
{"code_actions": {"source.fixAll.eslint": true}}}}}`
