Extended tag functionality using Flow Identity

[Bargestt]

This struct is an optional replacement for GameplayTagContainer to quickly navigate between world and graph
When your project has thousands of tags it is quite irreplaceable to quickly bind to desired actor or find what will be matched with node

I've tried to replace gameplay tag containers in nodes, but it turned to a much bigger change because core redirects are not enough
But by adding custom versioning old properties can be converted to the FlowIdentity struct without data loss

If you are interested, I can raise full replacement PR instead of keeping struct optional

Also, here is example why this struct is needed
Our level designers have no chill. 3400+ tags and some levels haven't left the blockout stage
Had to remove location names, not sure whether this'll break NDA otherwise, but just look at this madness
