Fix T57105: Baked Particles could not be rendered as expected

Same fix as for smoke (and is what caching proposal is AFAIK):
share cache between copied and original objects.

One thing which is still missing to be fixed is to make auto-cache
more reliable. It was already kind of broken, so don't think it
should be a stopping factor for this fix.

Workbench: Volume: Fix slice display opacity

GPU: Fix crash at startup

UI: move gpencil paint into topbar only layout

Tool properties were duplicating UI elements.

Cleanup: remove redundant checks

Cleanup: split object mode out of tool checks

Tool System: use enum for gp sculpt/weight paint

Fixes T57525

Cleanup: add arg to GP_EDITABLE_STROKES macro

Without this, we use arguments defined in the macro
making code hard to read.

Merge branch 'master' into blender2.8

Cleanup: use lowercase 2d/3d in function names

Cleanup: use doxy groups
