Creates a copy of a cache entry and returns it. Protects the original cache entry from modification, except for
the _pluginData property, which remains writable and can be accessed from the copy.

NB The `attribute` property is cloned and protected, too, if it exists.

@param   {CachedTemplateData} cacheEntry
@returns {CachedTemplateData}
