For object types, switch between single line and multiline display

[brettz9]

Motivation

Allow greater readability (or more condensed viewing).

Current behavior

Single and multiline object types are not auto-interchangeable. E.g.,

/**
 * @param {{a: string, b: number}}
 */

to:

/**
 * @param {{
 *   a: string,
 *   b: number
 * }}
 */

Desired behavior

Allow auto-adjusting of single and multiline object types, including auto-provision of indent when displayed mulitline.

Alternatives considered

None.
