docs: refine API docs for files in Utils dir

[devvaannsh]

Consistent JSDoc Format:
Changed /.../ comments to /**...*/ to maintain consistency and follow the correct JSDoc style.

Public API Documentation:
Added missing JSDoc comments to ensure public APIs are properly documented.

Separate JSDoc for Variables:
In ExtensionLoaded.js, FeatureGate.js, and Resizer.js, each variable is documented separately. This ensures accurate documentation, as only the first function or variable following a JSDoc comment gets picked up. Grouping multiple variables under a single comment causes only the first one to appear in the docs. This change doesn't affect existing code!

Internal Modules Excluded:
Removed EventDispatcher.js and Globals.js from the API docs since they are part of an internal module.

Please add the following missing files/changes too

• EventDispatcher.js
• KeyEvent.js - NB: Do not define constants out of the define block, it may break in safari.
• NativeApp.js
• NodeUtils.js
• TokenUtils.js
• UrlParams.js - not to be included in docs, but add a JS doc comment on top of this file saying that this is deprecated and use browser APIs for operating on URLs.
• ValidationUtils.js
• ZipUtils.js

[devvaannsh]

ValidationUtils.js and zipUtils.js files are already added in API docs. The jsdoc for those files seems fine. Doesn't require any changes.
