Depsgraph: Fix strict compiler error with copy on write disabled

Depsgraph: Fix particle system freeing accessing freed particle settings

Need to ensure CoW IDs are freed in the right order.

Eevee: SSR: Add roughness random rays.

Depsgraph: Fix heap use after free when freeing scene with compositor

This is the fake ID nature of compositor again. Need to discard such
pointers before freeing datablock even for scenes (before it was done
for objects only).

Depsgraph: Fix assert failure on Cycles render

Was happening when there was material in bmain but not used by any object.

Depsgraph: Fix remapping of node trees when they reference self material

Depsgraph: Add missing expansion od custom bone shapes

Depsgraph: Fix wrong ID remapping when armature object is constructed prior to it's targets

Previously it was possible to run into situation when armature is constructed prior to
objects which are used for it's constraints. This was causing wrong scene evaluation.

Now we create placeholders for objects used by armature in case they don't have ID node
yet, which ensures we have proper mapping from original to copy-on-write ID pointer.

Depsgraph: Ensure scene camera object is always built

Depsgraph: Add code which helps catching cases when requested ID node is not ready yet

This shows the bug when IK solver doesn't update reliably when targeted an external
object and when that object is handled by build_object() after the armature.

ID: Add run-time flag indicating that ID is coming from copy-on-write

Depsgraph: Fix compilation error in previous commit

Depsgraph: Remove hacky workaround for copy-on-write tagging flushing updates to everything

Wasn't working reliably,m and it's somewhat dangerous anyway. Seed something smarter.

Depsgraph: Fix crash opening file with IK solver with copy on write enabled

The issue was caused by id_copy_no_main() changing pointers of constraints used
in pose to a newly allocated ID. This is correct, but caused confusion too our
copy on write remapping, because we are mimicing inplace duplication by copying
memory over from a temporarily duplicated ID to a proper placeholder. This was
causing dangling pointers in pose to a temporarily allocated ID.

Now we add special code to remapping callback which replaces temporary ID with
a proper one.

Depsgraph: Restore ID datablock tag when Object is tagged with OB_RECALC_DATA

Was lost in one of the previous commits.

Depsgraph: Restore workaround for CoW objects not being fully expanded

Depsgraph: Prevent wrong particles state when canceling playback

Depsgraph: Fixes to make particle system behave more correct

Couple of main things here:

- Properly handle PSYS_UPDATE_* flags from DEG_id_tag_update.

There are still some possible issues here related on the fact
that we don't differentiate different PSYS_UPDATE_* flags here
and handle the mall the same.

Other possibility here is that object level particle settings
evaluation might be forced when particle system evaluation is
tagged for update. Didn't see actual issue here yet, but need
a closer look.

- Don't tag non-object datablocks on visibility changes.

Those don't depend on visibility anyway. This prevents particle
settings IDs from flushing updates to all objects, causing all
cached particles to be lsot.

- Only update translation and geometry components on visibility
changes.

Once again, this prevents particle cache from being invalidated.

We might need to tag material components here still tho.

Depsgraph: Stop tagging all IDs for update on depsgraph rebuild

This code needs to be changed. For the time being CoW might become less stable,
but need to stop doing such tag for other work.

Depsgraph: Initial implementation of more granular tagging

This commit makes it so that only ID components which correspond to the tag
flag are tagged for update (previously the whole ID would have been updated
in the most of cases).

This allows us to have more granular tag flags and prevent tagging of things
we don't want to be tagged.
