Falcata Exoskeleton (#21077)

This PR adds a new tier 1 exoskeleton to the hardsuit designs. I've been
bothered for awhile that there exist security hardsuit modules available
at roundstart, which cannot actually be used without science first
unlocking combat hardsuits, since normal hardsuits cannot use them. So
this PR adds a new exoskeleton(notably not a hardsuit, it offers no
space protection!), which serves to provide a means of putting those
tier 1 security modules on something, without invalidating the later
combat hardsuits(which are all significant upgrades over this).

Many of these lower tier security modules were essentially invalidated
by higher tier sec modules that would get unlocked alongside actual
combat hardsuits.

The falcata exoskeleton has the same armor values as security's heavy
body armor, essentially meaning its primarily only an upgrade over said
armor in the sense that it lets the wearer use the shoulder mounted
taser module.
