Make JSDoc formatting more consistent (#9796)
A few inconsistencies in JSDoc formatting have been fixed throughout
the project. Many issues remain; these were just the few things that
were easy to fix with a regular expression.

The changes include:

* Using lower-case for primitive types, but capitalizing non-primitive
 types
* Separating the parameter identifier and the description with a dash
* Omitting a dash between the return type and the return description
* Ensuring the parameter type is first and the identifier is second (in
 a few places it was backwards)
* Using square brackets to denote when a parameter is optional, rather
 than putting "(optional)" in the parameter description
* Including a type and identifier with every parameter
* Fixing inconsistent spacing, except where it's used for alignment
* Remove incorrectly formatted `@deprecated` tags that reference non-
 existent properties
* Remove lone comment block without accompanying function

Additionally, one parameter was renamed for clarity.
