Modifiers: Port mesh_calc_modifiers from DerivedMesh to Mesh

This ports the main modifier eval loop.

A few things haven't been ported yet: tessface and shapekey related code. As
far as I can tell, shapekey code was never entered into.

https://developer.blender.org/D3342

Add modifier_deformVerts_ensure_normals, modifier_applyModifier_ensure_normals

Same as `modwrap_deformVerts` and `modwrap_applyModifier` but for `Mesh`.

Add BKE_mesh_is_valid

Non modifying version of `BKE_mesh_validate`, mirrors `DM_is_valid` more
closely. Will be used in port of `mesh_calc_modifiers`
from `DerivedMesh` to `Mesh`.

Particle system: get current time from depsgraph

This makes the particle animation work again!

Workbench: Read studiolights from USER + SYSTEM datafiles

Fix navigate widget w/ region overlap

Fix visible region overlap calculation

Existing code didn't account for top/bottom overlap.

Transform: Snap: Make sure if bmesh arrays need to be recalculated.

Scene raycast: The return index should indicate the polygon instead of the looptri.

This was the default behavior and could break some addon since looptri is almost useless for the current python API.

Merge branch 'master' into blender2.8

Workbench: send right event after shadow_shift changes

Revert "BLI_kdopbvh: Reference clip_planes callback to find nearest projected."

This reverts commit 717dd4cecd2ea8eaa7b3bbfb5a5c7ec65f0337c0.

It was causing problems in the protactor ruler.
I'll think of a better solution.

Fix T55032: Redo w/ file saved in edit-mode failed

It's important edit-mode has a step stored for redo to work,
file load now ensures this in a generic way.

Cleanup: pass the use_depth parameter to the `SnapObjectParams` struct in the ED_transform_snap_object_project_view3d_mixed.

BLI_kdopbvh: Reference clip_planes callback to find nearest projected.

Clip_planes are an important parameter to be used in callbacks.
