Provide a Configuration to Generate Object Type Declaration Members in List Mode

[capraynor]

Hi, I'm about to create a configuration:

objectTypeDeclarationStyle: "table" | "list". 

This configuration behaviors like the following:

When objectTypeDeclarationStyle == "table": (default value)
The "Object Type Declaration" (the type declaration that have children) will be rendered as table.
The "Call Signature Type Declaration" will works as before.
The "Union Type Declaration" will works as before.

When objectTypeDeclarationStyle == "list":
The "Object Type Declaration" (the type declaration that have children) will be rendered as list, just like current behavior of class properties.
The "Call Signature Type Declaration" will works as before.
The "Union Type Declaration" will works as before.

Will submit my PR with test spec later.

If use objectTypeDeclarationStyle == "list":

The rendered result will be:

And the multi line comment will shows like:
