feat: set prioritization by set type (#5097)

* feat: prefer 'Core' and 'Expansion' sets for prioritization

* rework set prioritization

* clean up priority enum

* formatting

* revert changes to CockatriceXml3Parser

* re-add missing null check

* remove priority fallback ternary from CardSet model

* make defaultSort logic easier to follow

* revert changes to v3 card database xsd

* remove unused invisible priority col from sets dialog

* move draft innovation and duel deck sets to secondary prio

* minor fixes

* change PriorityFallback to 1

* make priority optional in xml

* remove PriorityUndefined and set PriorityFallback to 0

* set priority when not found to PriorityOther

in case a new set type is added it's unlikey we want it sorted first,
it'll probably be a new product so it's probably best to sort it with
the funny things

* simplify sort function
