Avoid needing to call uasort so many times when building forms

I'm shocked at it being called 413 times because of Metatag, that seems excessive. How many tags were available on the site?

Would the correct approach be to override getDefinition() in the two plugin discovery classes and sort them there?

I did some testing locally and from what I can see on a cold cache load of a single node page it only runs uasort() once for each tag group plus once more to sort the groups. So in your example were there 412 tag groups?

I'll try to do some more debugging vs just reading calls from the Blackfire graph and report back. We also have several Metatag contrib running.
