Fix missing HE magazine for Blackfish Autocannon.

[xrufix]

When merged this pull request will:

• Adds magazine from HE muzzle to AP muzzle for Blackfish Autocannon (autocannon_40mm_VTOL_01)
• Removes muzzle tweak from all autocannons in ace_vehicles to fix problems with inheriting from autocannon classes.
• Fixes Black Fish bushmaster issue #5847
• Changes displayName to "L/60 Bofors Autocannon". See reason below.

I would also change the displayName to "L/60 Bofors Autocannon" in realisticnames. This is the cannon currently used on the AC-130 and resembles the ingame model. Compare attached screenshot with real life counterpart (source: https://upload.wikimedia.org/wikipedia/commons/b/bc/Bofors_guns_on_Spectre_gunship.jpg).

class autocannon_40mm_CTWS: autocannon_Base_F {
    class AP: autocannon_Base_F {
        magazines[] = {"40Rnd_40mm_APFSDS_shells","40Rnd_40mm_APFSDS_Tracer_Red_shells","40Rnd_40mm_APFSDS_Tracer_Green_shells","40Rnd_40mm_APFSDS_Tracer_Yellow_shells","60Rnd_40mm_GPR_shells","60Rnd_40mm_GPR_Tracer_Red_shells","60Rnd_40mm_GPR_Tracer_Green_shells","60Rnd_40mm_GPR_Tracer_Yellow_shells"};
        magazineReloadTime = 0;
    };
    muzzles[] = {"AP"};

For the apc cannon we move all the magazines to the AP muzzle and then disable the HE muzzle.
I'm not really sure why, moves ammo type switch to action menu instead of F key?

For the VTOL: we could also just restore the original muzzle config muzzles[] = {"AP", "HE"};

[xrufix]

I don't know why that's done either, but decided to mimic it because of consistency. Otherwise i would have prefered muzzles[] = {"AP", "HE"};.

I'd say we just remove that muzzle tweak. Was something Flummi did for APC's years ago (AGM), but since then many new assets have been added without anyone updating this.
I think it just causes problems at this point.

[xrufix]

Then i'll remove it.
