Make it easier to delimb extremities, make it harder to delimb core

About the PR

• instead of parts having a uniform slash threshold hands, legs, arms, feet, head, etc. now have separate thresholds for falling off
• hands fall off at 25 slash
• arm falls off at 40 slash
• leg falls off at 80 slash
• foot falls off at 40 slash
• head falls off at 100 slash

Why / Balance

• razorium can just make people instantly explode all at once when they hit the threshold atm, this makes the process more gradual
• if every part takes the same amount of effort to fall off there's no reason to target anything other than the head
• make it more likely that surgeon will have more things to do that aren't reassemble someone that totally fell apart

Technical details

• remove the destructible from BasePart because of prototype inheritance order concerns
• new parents for a bunch of the base parts w/ the destructible components

Requirements

• I have tested all added content and changes.
• I have added media to this PR or it does not require an ingame showcase.

Breaking changes

Changelog

🆑

• tweak: Extremities such as hands and feet are now easier to hack off in combat, whilst core things such as arms, legs, and heads are more difficult to hack off
