RFC: Support for dot syntax on @param

I'm currently working with d.ts files where methods taking object parameters are documented with the following approach:

/**
* Method description.
* @param options addItemOptions - e.g. { id: 1234, title: "someTitle" }
*             id: The unique identifier.
*             title: The title to assign.
**/

It's challenging to parse and auto-generate documentation for these parameters given this approach. Ideally there'd be support for dot syntax e.g.:

@param options.id - The unique identifier.
@param options.title - The title to assign.

Start with the proposed @param options.id and options.title syntax and review the 25-comment discussion. The issue names no implementation files or tests, so first locate the relevant TSDoc specification and parser entry points. Done means defining and implementing the syntax consistently, with coverage for nested parameter documentation.
