Tweak ID->tag reset on file load (no visible change expected!).

Issue was, *some* IDs (like infamous nodetrees from materials etc.)
would not go through the 'main' read_libblock() func, so their tags were
never reset.

So now, we ensure direct_link_id() always clear the tags, and move
setting them in read_libblock() after the call to direct_link_id().

Needed for depsgraph, but general healthier fix actually.

Depsgraph: Get pchan index from correct pose

This code should be replaced with evaluation-time ID block expansion,
but before that it will be helpful to get old design to work again.

Depsgraph: Ensure root pchan is always found

Depsgraph: Pass CoW version of object to armature update done

Fix part of T53497: Eevee stuttering on macOS for the first few seconds of usage.

The problem was that textures were assigned to different slots on different draw
calls, which caused shader specialization/patching by the driver. So the shader
would be compiled over and over until all possible assignments were used.

Fix missing hair in fishycat and everything else after particle recalc changes

The cache was getting reset always, due to special case of flag being 0.

Depsgraph: Add missing expansion od custom bone shapes

This was fixed in 2.8 branch but not in master.

Depsgraph: Only bind ID-data and indices to depsgraph callbacks

This is a part of copy-on-write sanitization, to avoid all the checks
which were attempting to keep sub-data pointers intact.

Point is: ID pointers never change for CoW datablocks, but nested
data pointers might change when updating existing copy.

Solution: Only bind ID data pointers and index of sub-data.
This will make CoW datablock 7update function was easier in 2.8.

In master we were only using pose channel pointers in callbacks,
this is exactly what this commit addresses. A linear lookup array
is created on pose evaluation init and is thrown away afterwards.

One thing we might consider doing is to keep indexed array of
poses, similar to chanhash.
