Share a lot of similar checks with TargetRestriction and similar flags

I try to move the whole logic into a `SpellAbility::cantTargetMsg` function that returns a String if the target would be fail
so `canTarget` returns true if the String is null

Affected from this are these StaticAbilties:
* StaticAbilityCantTarget
* StaticAbilityCantAttach

i want them to have functions to return the First StaticAbility where the condition is true.
so the `cantTargetMsg` can be which Static/Keyword is causing it to not be targeted Shroud/Hexproof/Protection
