…ve cores uninstalled [MDB IGNORE] (#24556) (#255)

* Adds a var to determine if anomaly-locked MOD modules can have cores uninstalled (#79171)

## About The Pull Request
Title. The `core_removable` var on the `anomaly_locked` MOD module
typepath now determines if a core can be removed post-installation. This
isn't used anywhere, at the moment, but could be used to, say, prevent a
space-loot MOD module's core from being removed for other purposes.

Adds `/prebuilt/locked` subtypes to the currently present and defined
anomaly-locked modules, which have this var enabled, and puts them
nowhere else.

## Why It's Good For The Game
Another way to control distribution of anomaly cores - making people
commit to having a limited-supply item installed in a thing, or
something like that.

For habitual Github-readers, this is *unused*, at the moment, just
something that could be used by another coder down the line or
something.

## Changelog

:cl:
add: Anomaly-locked MODsuit modules can now be varedited to have
unremovable cores, or can be spawned with this functionality by using
the /prebuilt/locked subtype.
