Convert vehicle hardpoints from using their bespoke firing system to one structured closely on handheld guns and deployables such as the M2C. Now using the autofire component. Much like handheld weapons it is capable of different firemodes (semi/burst/auto) and changing targets during fire.

Hardpoints were converted to match their old effectiveness as closely as possible; this is intended as a quality of life improvement, not a rebalance. Damage, AP, range, ammo, etc were not touched.

Fire rates were copied over directly. Single-fire weapons with long delays were made semi-auto (e.g. LTB), and those with short delays were made full-auto (e.g. autocannon). Burst-fire weapons with significant extra delays after the burst remained burst-fire (cupola, smokescreen), and the rest were converted to full-auto (e.g. dual cannon). While changing firemodes is easily implemented, no weapon seemed a good candidate for more than one firemode and so that is omitted for now.

Scatter was approximated. The existing accuracy functioned as a percent chance the shot would stray one tile from the target. Gun-style scatter is instead a cone of fire in degrees. No direct conversion is possible, so scatter values are roughly set such that firing at a tile at the edge of the screen should "feel" about as accurate. Closer ranges would experience less spread than before, longer ranges more.

The buffing weapon sensor module was adjusted to work with the new firing system, and effects hardpoint scatter angle and firing rate. Vehicle buffs still use multipliers instead of adding/subtracting as handheld guns do, as a flat +/- adjustment to fire delay would have a significantly different effect on slow firing weapons (e.g. LTB) vs fast firing (e.g. autocannon). One major difference is that burstfire delays are effected and buffs increases the burst density. Before, there was a single cooldown initiated at the start of the burst, and only that cooldown was modified by the buff. Now, since the inter-burst delay is needed by the autofire component both the inter-burst delay and the after-burst delay are modified by buffs.

Activating non-selected hardpoints was removed as not compatible. The issue is that tracking a single click's modifiers is no longer sufficient, it has to track through the whole mousedown-to-mouseup period and the user can change multiple click modifiers in that time. I could not find a method that was satisfactory without a much bigger overhaul of vehicle controls than I'd like to take on in a PR not meant for it. I'm sure it can be done, but that brings up the question of if that's even the control scheme we'd want, in a PR that was never meant to ask that question let alone answer it.

Explain why it's good for the game

Vehicle weapons using gun-like code makes them easier and more familiar to use, and more code commonality makes maintenance just a little bit easier.
