Short R3F compat update according with the new AB drag models

[Laid3acK]

• Revert to the default G7 drag model for the 5.56x45 and 7.62x51 bullets.
• Update all airFriction according with the new ACE3's ones.

Merge after #5566?

Doesn't have to be after #5566 But wouldn't hurt.
No dependencies here.

Yes that's what I meant, it will work better after #5566, in case of any issues that might prevent merge of it (hope not!).

The R3F airFriction are designed to work with the vanilla ballistic (R3F SCROME scopes and BDC reticles).
The ballistic in-game is more accurate with the old or the new ACE3 airFriction in all cases.
So, you can merge it when you want : now, after #5566 or with the ACE3 3.12.
It's not really a problem, the result in-game will be necessarily better with the ACE3 values. :)
