EXT-7777 WIP Added several cases to show Loading indicator in "My Outfits:"

* Outfit is loading for the first time
* After user clicks:
 ** Item Context menu > Add
 ** Item Context menu > Replace

Known Issues:
1. For multi-wearable indicator will disappear after first item from the batch is worn.
   Did not fix this to not affect the stability before 2.1 release.
2. To show loading indicator first time we have to notify subscribers of LLAgentWearables.
   For now this is done from the deprecated LLAgentWearables::processAgentInitialWearablesUpdate
