Tool System: transform can now toggle loc/rot/scale

UI: Changes in Specials and Deleet menus

Depsgraph: cache effector relations, for performance and stability.

To find all effectors in the scene, we need to loop over all objects.
Doing this during depsgraph evaluation caused crashes because not all
objects are guaranteed to be evaluated yet.

To fix this, we now cache the relations as part of the dependency graph
build. As a bonus this also makes evaluation faster for big scenes,
since looping over all objects for each particle system is slow.

Fixes T55156.

Cleanup: nuke (nearly) all remaining usages of DM from RNA.

Only case remaining is a nasty ccgdm/opensubdiv update case, TBD once
subsurf case is addressed.

Port DM_debug stuf to BKE_mesh_runtime.

Merge remote-tracking branch 'origin/blender2.8' into temp-eeveelightcache

Eevee: LightCache: Fix sample selection algorithm

DRW: Modify the engines code to work with latest changes

Fix crash reading toolsettings

DRW: Refactor ObjectEngineData into DrawData

This is because we will use it to store the update flags from the depsgraph.

Use a similar system as AnimationData where the struct is inserted at a
fixed position after the ID struct.

Cleanup: use standard BKE_object_free_derived_caches in BKE_mesh_to_curve.

...Instead of doing own dirty/risky version of the same thing!

Cleanup: misc DrivedMesh stuff.
