Disable dynamic_vram when weight hooks applied (#12653)

* sd: add support for clip model reconstruction

* nodes: SetClipHooks: Demote the dynamic model patcher

* mp: Make dynamic_disable more robust

The backup need to not be cloned. In addition add a delegate object
to ModelPatcherDynamic so that non-cloning code can do
ModelPatcherDynamic demotion

* sampler_helpers: Demote to non-dynamic model patcher when hooking

* code rabbit review comments
