[MIRROR] Makes simple bodycam component COMPONENT_DUPE_SELECTIVE (#…

* Makes simple bodycam component `COMPONENT_DUPE_SELECTIVE` (#82310)

## About The Pull Request

The thought only just occurred to me people may want to throw multiple
bodycams with different networks on them onto one mob, and it would be
trivially easy to support, so here.

I used `COMPONENT_DUPE_SELECTIVE` rather than `COMPONENT_DUPE_ALLOWED`
so people can avoid adding two of the same camera (network) to one mob.

* Makes simple bodycam component `COMPONENT_DUPE_SELECTIVE`
