Fix break on duplicated instances since IDNodes depsgraph iterator

Remove "Group Collection" functionality

This may get "double-reverted" in the future. But we want to separate this
from the main patch before merging it. And then eventually merging them
separately.

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

macOS: remove old OpenMP lib stuff from cmake

Depsgraph: Iterates over ID Nodes instead of Bases

Although this works by itself, it should actually happen after:

"Reshuffle collections base flags evaluation, make it so object is gathering
its base flags from collections."

Meanwhile we have one single hacky function (deg_flush_base_flags_and_settings)
to be removed once the task above is tackled.

Eevee: Remove uses of DRW_shgroup_call_dynamic_add_empty in shadows and probe rendering.

This was adding an unecessary high number of DRWCall per objects.

DRW: Use pseudo persistent memory pool for the rendering data structure.

This gets rid of the bottleneck of allocation / free of thousands of elements every frame.

Revert moving includes to fix linux linking and just change linkorder again

Fix problem after merge

One BKE function used changed

Rename ID_IS_LINKED_DATABLOCK to ID_IS_LINKED.

This makes code closer to id_override/assent-engine ones, which
introduce a new type of linked data, and hence reserve
ID_IS_LINKED_DATABLOCK to real linked datablocks.
