Adds regenerate_organs proc and adds it to relevant regeneration code (#22740)

* Adds regenerate_organs proc to carbon and adds it to relevant regeneration code

I simply took the bit from the admin heal and made it into a proc and
added it to the necessary regeneration-related bits of code.

* Adds regenerate organs back to fully heal

For some reason this didn't get included in the previous commit.

* moves regenerate_organs to organ_internal

As suggested. It fits better here, anyways.
