Refactor inputs - Githubissues

Refactor ucupaint inputs to use native node socket when available so it will work better with keyframe and driver. This refactor will make sure all calculations are done in shader rather than python code.

[ ] Mapping (check if input props are actually needed)
[x] Channel Intensity Value
[x] Normal bump distance
[x] Transition Bump Distance
[x] Transition Bump Edge Multipliers & Factors
[x] Transition Bump Falloff props
[x] Transition Ramp props
[x] Transition AO props
[x] Layer channel props (including bump_smooth_multiplier)
[x] Mask props (including Color ID)
[x] Channel override props
[x] Layer props
[x] Modifier props
[x] Mask modifier props (No need since there's no float properties)
[x] Normal Map modifier props
[x] Root channel props
[x] Make sure the update process on the old node setup works ( NOTE: There's more than one type of intensity multipliers now)
[x] Make sure the system works with keyframes or drivers
[x] Make sure keyframes and drivers are also deleted after deleting the entity
[x] Make height tweak toggle and it should only affect height before baking
[x] Dealing with normal height input (smooth bump will use a bit of hack)
[x] Make sure fake lighting normal input works with new system (flat normal only for now)
[x] Make enable subdiv behave non destrutively, see channel alpha for inspiration
[x] Check out for adaptive and subsurf only option for displacement setup
[x] Dealing with different adaptive subdiv normal for Blender 2.93 or lower
[x] Bake to layer no longer need to use baked displacement
[x] Add root channel smooth bump factor to tweak the normal without tweaking the height
[x] Make layer preview works with subdiv setup
[ ] Dealing with parallax since it probably won't be possible anymore without baking
[ ] Remove support for displace modifier subdiv method, use adaptive only for blender 2.79
[x] #127
[ ] Make cavity baking works with subdiv setup
