* Support property declarations in jsdoc template generation

* fix lint and add test

* Fix jsdoc comment parsing initial state

Jsdoc comment parsing can be invoked in two modes:

1. top-level parsing, for comments not inside a tag.
2. tag parsing, for comment that occur after the semantic parts of a
tag.

Top-level parsing skips an initial * because it assumes that it is starting
at the very beginning of a JSDoc comment. Tag parsing does not.

The two modes are distinguished by an optional second parameter named
`margin`. When `margin` is provided, it provides an initial indent used
for comment alignment.

Previously, the check for `margin` was a truthy check `if (margin)`.
This check incorrectly treats `margin=""` the same as
`margin=undefined`.

This PR changes the check to `if (margin !== undefined)`, which
correctly treats `margin=""` the same as `margin="    "`.

* Fixes for broken tests

1. Use SawAsterisk start state.
2. @template needs to skip asterisk in addition to whitespace while
parsing type parameter names.

* undo code move
