Refactor SpiceBloom

- Remove SpiceBloom.RespawnDelay

It is basically redundant (giving the spice bloom spawner a longer
self-kill delay at yaml level has the same effect) and uses the savegame-blocking DelayedAction, so just removing it is the cleanest solution.

- Rename SpiceBloom GrowthDelay to Lifetime

- Refactor spicebloom.spawnpoint to not use SpiceBloom trait and make it visible in editor with corresponding tooltip.
