Add ammoConsumedPerShot to ammosetdefs

[perkinslr]

Additions

Describe new functionality added by your code, e.g.

• A new field is added to ammoSetDefs to support modifying ammo used per shot across entire ammosets. Mostly matters for vehicles.
• The existing per-verb property is left unmodified, but the effects multiply

Reasoning

• Vehicles do not have ammosets, so moving the value to the ammoset is the simplest way to expose the data for VF use.
• Multi-verb frameworks might want to set different values for different verbs, so removing the value from the verbs is probably a poor choice.

Alternatives

Describe alternative implementations you have considered, e.g.

• Explicitly add a separate mult value for vehicles to use
• Disable the per-verb value

Testing

Check tests you have performed:

• Compiles without warnings
• Game runs without errors
• (For compatibility patches) ...with and without patched mod loaded
• Playtested a colony (specify how long)
