Shotgun spread refactor Cherry Picked

[VividPups]

About the PR

This is Cherry-picked from this PR https://github.com/space-wizards/space-station-14/pull/27773 (I'm not quite sure how to give Proper credit and whatnot to the OG people)

Why / Balance

Needed for a guns

Testimonial

" I added a new component, ProjectileSpreadComponent. The new component now holds the projectile count and spread data that was previously in the CartridgeAmmoComponent, as well as an additional entity prototype field. In the GunSystem, the code for spawning the original bullet uses the switch case's preferred method (spawning the bullet from the cartridge prototype for CartridgeAmmoComponent and just launching the projectile it already has for AmmoComponent) but uses the ProjectileSpreadComponent to launch the rest of the spread. " - RiceMar1244

Should be fine, tests seem alright, clamp is still wonky, unsure why - projectiles will never hit unless user is within 1 m of the mob.
