Fixes a bitrunning runtime & adds a component initialize result (#90099)

## About The Pull Request
Noticed that bitrunning virtual spawners were runtiming if the server
was already emagged. Basically, the guardrail component is added
(virtual_entity), then immediately deleted because it's emagged, leading
to a race condition in `JoinParent()` where parent is null. I still want
to keep this "valid, but delete me" state for components, so I made
`COMPONENT_REDUNDANT` (thx @LemonInTheDark).

I can't say for certain because I couldn't repro, but this /probably/
fixes #89992
## Why It's Good For The Game
Fixes a runtime
Allows devs to add components that execute an arbitrary amount of logic
while still qdeling themselves due to some in-game incompatibility issue
