Update #[min/max] node macro attributes to #[soft/hard]_[min/max] and make them clamp their input data (#2464)

* Fix min and max macro not enforcing limits when data flows

* Use trait based clamping

* Remove min/max from testing

* cargo fmt

* Resolve into min, and hard_min

* cargo fmt

* fix traits

* cargo fmt

* fix tests

* rename as soft_x

* Add validation code

* Clean up (not compiling because of DVec2 clamping)

* Avoid needing to add trait bounds to node definitions

* Code review
