Rule for object curly brace new line

```
type Obj = {
test: number };
```
The above should error and instead be fixed to
```
type Obj {
test: number,
};
```

Rule that does patterns similar to this https://eslint.org/docs/rules/object-curly-newline

Start by comparing the requested Flow object-type formatting with ESLint's object-curly-newline rule, linked in the issue. Use the two examples as the expected error and autofix behavior; done means the rule handles this pattern consistently and verifies both outcomes.
