This PR is a general overview and cleanup of some code structure and doc blocks in the admin com_cache component. This also updates a couple of doc blocks in the JCache class chain to reflect the correct return types (traced while reviewing this component's code) Changes of note:
Doc blocks cleaned up some to follow standard
Return the results of the view's display() methods to be consistent with the documented return
Not using variables for items only referenced once
Use Joomla\Utilities\ArrayHelper instead of JArrayHelper
Testing Instructions
The admin com_cache component should continue to function correctly
