[Javascript APIView] Inline object type formatting for method parameters is misleading

**Bad code snippet:**
```javascript
toJSON(options?: { preserveCase?: boolean; }): RawHttpHeaders;
```

**Issue:**
APIView renders the method parameter's object type inline, which can be misleading for larger or more complex option objects. This formatting is a result of APIView's rendering, not a guideline or code issue. For improved readability, especially as more properties are added, a multi-line format should be used.

**Good code snippet:**
```javascript
toJSON(
options?: {
preserveCase?: boolean;
// additional properties here
}
): RawHttpHeaders;
```

APIView should render object types for method parameters in a multi-line format when the object is or may become complex, to improve readability.

The issue concerns APIView rendering of JavaScript method-parameter object types; start by locating the APIView parser or renderer entry point for this formatting and compare the bad and good snippets. Done means complex object parameters render across multiple lines without changing the API signature.
