-Reverting one part of the change to fix cook on the fly with plugin extensions that add supported target platforms. The fact that the reference platform list is often empty, and that empty list = all platforms meant this was letting through incorrect plugins in some cases. Further testing revealed that while the platform extension plugin is rejected here by the previous code it is picked up later on in cook-on-the-fly.

-First problem: we were filtering out plugins based on the FPlugin, rather than the FPluginReference. This meant that the platform extension platforms were not in the supported list. Needed to use the FPluginReference in that one spot.
-Second problem: platform extension .uplugin files were not added to the file list for the NetworkFileServer because we find Plugins separately specifically looking for the basedir of each plugin. In order to find these files I am caching the basedir of each child plugin in the FPlugin when we merge the children into it. NetworkFileServer can then find these directores, examine them to see if they are not for the targeted platform, and make them available to the client.

GetLocalizationPathsForEnabledPlugins will now avoid loading any plugin modules (from its previous call to ConfigureEnabledPlugins), and any plugins that become enabled between GetLocalizationPathsForEnabledPlugins calls will explicitly notify that their localization data is available (as already happens for explicitly loaded plugins).

This change takes the existing async loading that was added for game localization data in CL# 14661627 and expands it to cover all localization data. Async localization tasks are chained together as dependencies to preserve the existing order of operations (plus going wide doesn't help due to contention on the live-table), and can be waited on at any point (eg, after a loading screen) by calling FTextLocalizationManager::WaitForAsyncTasks (though the engine init flow takes care of waiting for you unless you're loading additional plugin/chunked localization data).
This change takes the existing support for dynamically loading chunked localization data on PAK chunk load, and extends it to support dynamically loading any additional localization data. This is used by the engine to support dynamically loading the localization targets associated with explicitly loaded plugins. These loads are all async, so must be waited on if you need them to block.
Note: BeginInitGameTextLocalization and EndInitGameTextLocalization have been removed as part of this change. You would now just use InitGameTextLocalization (which is async) followed by FTextLocalizationManager::WaitForAsyncTasks.

When refershing the plugins list, we start by clearing unused plugin enteries. This change does this for unmounted (explicitly-loaded) plugins too.

Instead, expanding the explicit mounting behavior, providing alternative signatures to MountExplicitlyLoadedPlugin(), encouraging users to use the already established way of dynamically mounting plugins.
