Consistent jsdoc syntax (#7755)
* Specify type before parameter name

Various JSDoc `@param` entries were specified as `name {type}` rather
than `{type} name`.

A couple of `@return` entries have been given types as well.

* Use JSDoc optional syntax rather than Closure syntax

* Use @returns rather than @return

* Use consistent built-in type capitalization

Primitive types are lower-case, and Object is upper-case.

* Separate param/return description with a dash
