Replaces flamethrower unique hit_reaction handling with the bullet_intercepting component (#92731)

Browse Source 
## About The Pull Request

Flamethrower exploding when shot was handled by hit_reaction previously,
and will now use the generic bullet_intercepting component. Also adds
handling for multiple projectile types in the bullet_intercepting
component, as well as a check for whether the object currently can block
bullets. Should have no gameplay changes.

## Why It's Good For The Game

closes #81863 , they said it'd be better consistency
