* [LYN-2522] Preparation work for the filter pane
* Added arrow up/down icons.
* Extended the gem info with the type (Asset, Code, Tool).
* Extended the model with the type and a helper for converting gem uuids into display names.
* Extended the link widget to be clickable with a custom action, needed for the "Show all/less" for the filters.
* Converting the uuids we get from Python to AZ::Uuids and then back to strings to have them all in the same format.
