Evaluate and rework the categories of UEF naval units

Introduces the WEAK... categories to various units. Also removes the NUKE category from the strategic bomber as it is... not a strategic unit.

What I found interesting is that the ANTINAVY category actually means anti submarine. Weapons that are anti navy are torpedo-like weapons.

@relent0r / @maudlin27 please evaluate these category changes to make sure they do not mess with your AI 😃 !

Especially the removal of ANTINAVY from the Battlecruiser and the Destroyer. They still have the overlay and the WEAKANTINAVY categories, but they do not deserve the ANTINAVY category.

This one I don't love, its going to cause problems when trying to analyze if destroyers can deal with submarines or attack an underwater unit.

I'd also debate if they are considered weak antinavy, but I'm no expert there.

The destroyers of the UEF are definitely not made to fight submarines. It's intentionally weak because of the Torpedo Boat.

Do you have snippets of code where you analyze what a unit can (not) target?

[relent0r]

An example of the use case would be something like this.

PlatoonTemplate {
Name = 'RNGAI Sea Hunt',
Plan = 'StateMachineAIRNG',
GlobalSquads = {
{ categories.MOBILE * categories.NAVAL * categories.ANTINAVY, 1, 10, 'Attack', 'GrowthFormation' }
},
}

This is used for taking out under water mexes and dealing with submarines. With this change the AI would never form this platoon if only destroyers were available, even though a destroyer can tank enough damage to take out multiple submarines attacking its units without much trouble.
But thats more of a balance debate than a functionality one. You could apply the same logic to frigates since they have weak aa, but then if you've got a group of frigates and someones using t1 bombers to destroy them your not going to pack up and go home as they can tank the damage and dish out enough to kill the bomber/s.

So for this PR I would need to add another category to a platoon former like this is all. Not the end of the world and not a major inconvenience.

@relent0r I've re-introduced the ANTINAVY categories. We can look into that separately in the future if the need arises. Thank you for your time on the responses
