Remove dead mods: Tankmod

[anothersimulacrum]

Summary

SUMMARY: None

Purpose of change

Remove obsolete mods. I figure it's been long enough that old saves won't be a problem, but I could be wrong.

Describe the solution

git rm -r obsolete mods

Describe alternatives you've considered

Waiting longer.
Adding the mods removed to the mod test blacklist. I decided against this to prevent merge conflicts, it can be done later.

@Soup-de-Loop moved treads from blazemod to this mod in #40067, is it really obsolete now?

[Wishbringer]

Also #40067 fixed turret mounts in Tanks mod, so even though it's marked as obsolete I believe it to be functional now.

[Soup-de-Loop]

It is obsolete but in its current implementation still outdated. The fix was a going-forward sort of once off-thing for legacy users. I'll host a snapshot of it on my repo, but it can be considered properly terminated as a mainline inclusion because the implementation is hacky and not particularly plausible, both in how the vehicle parts operate and the prevalence of relatively undamaged and usable military vehicles strewn all over the place.

There is interest in providing true continuous track support at some point on vehicles, at most right now it's a task of collecting enough data to be able to draw conclusions from which to model.

I'll be trying to make a similar-but-different idea stemming from it, as short single-section continuous tracks such as those featured in half-track vehicles and small earth movers as a first-step in gathering data and basic implementation investigation.
