[Feature] Support editorconfig

Support https://editorconfig.org

instead of this

```ts
spotless {
// optional: limit format enforcement to just the files changed by this feature branch
ratchetFrom 'origin/main'

format 'misc', {
// define the files to apply `misc` to
target '*.gradle', '*.md', '.gitignore'

// define the steps to apply to those files
trimTrailingWhitespace()
indentWithTabs() // or spaces. Takes an integer argument if you don't like 4
endWithNewline()
}
```
you could simply do

```kotlin
spotless {
editorConfig()
}
```

which would simply figure out all the same information, and also presumably pass it to other things like

```kotlin
spotless {
java {
}
```
would inherit it.

possibly code or coordination of a general library for editor config in java here.
