Alembic: added Points exporter for particles

Depsgraph: Add IDProperties handling.

Fix T75279: BLI_assert failed when deleting object in debug build
(only).

And all general cases of ID pointer idproperties that would use a
data-block not referenced anywhere else in the depsgraph.

This includes idproperties from:
* All ID types;
* Bones and pose bones;
* Sequences;
* Nodes and sockets.

Differential Revision: https://developer.blender.org/D7551

IDProperties: add a foreach looper and use it in libquery code.

Note: part of fix for T75279.

Alembic: Pass correct `export_name` to the writers

The `HierarchyContext::export_name` was set to the object name, and not to
the last component of `HierarchyContext::export_path`. This doesn't matter
for USD, but it does influence the Alembic writers.

Alembic: improved logging

Cleanup: Alembic, renamed some variables in ABCNurbsWriter::create_alembic_objects

No functional changes

Cleanup: Alembic, made AbstractHierarchyIterator::get_object_data_path protected

There is no need for this function to be called from outside the class
hierarchy.

No functional changes.

Cleanup: Alembic, explicitly assign to named fields

This makes it possible to search the code for a field name and find where
it is initialised.

No functional changes.
