* [NodeDef] Explicitly add control_after_generate to seed/noise_seed

* Update comfy/comfy_types/node_typing.py

The idea is that you can indicate how much quality vs speed you want.

At the moment:

--fast 2 enables fp16 accumulation if your pytorch supports it.
--fast 5 enables fp8 matrix mult on fp8 models and the optimization above.

--fast without a number enables all optimizations.
