Fix T71909: Any keyframed GPLayer property is not updated when render animation

By error, the original datablock was used while rendering. Actually, only while the user is drawing the original data must be used because when we tested, the time the system uses to copy the datablock created a very bad "lag" feeling while drawing. Maybe the lag was half second only, but it ruined the pencil feeling.

I talked some time ago with Sergey about that and we decided use this approach.

Now, only the original datablock is used while the user is "moving" the pen, but not in any other situation.

Thanks @sergey for help me with this bug and sorry for thinking it was a depsgraph issue.

USD: avoid term 'original' in non-CoW context

Instead of 'original object' the code now mentions 'source' or
'duplisource'.

USD: renamed `prune_the_weak` ? `remove_weak_subtrees` + arguments

USD: rename `link` to `dupli_object` and made variable loop-local

I added an explicit `!= nullptr` to make the formatter put the three parts
of the `for`-statement on three different lines (instead of two), which
increases readability.

USD: made `bool weak_export` `const`

USD: removed terminal colour codes

USD: add unit test to test `HierarchyContext::operator<()`

USD: nicer structure for tests/gtests/usd/CMakeLists.txt

This structure makes it easier to add new test source files, and avoids
using a temporary variable.

Merge branch 'master' into greasepencil-object

add accessor functions for inlined node tree

add clusters to inlined node tree dot export

Fix crash caused by copy pasting!

Fix FXAA alpha issue.

We just take the full RGBA color instead of packing the luma in alpha.

USD: clarified ownership of objects returned by create_xxxx_writer()

USD: renamed should_visit_duplilink() to should_visit_dupli_object()

change cluster usage in dot exporter

USD: clarification of NULL-safety of `get_object_(data_)name`

USD: explicit typedef for `ExportGraph::mapped_type`

Cleanup: Naming conventions, code clarity mentionned in review

Fix T71860: No versioning for drivers in Mapping node.

The new Mapping node was missing versioning code for drivers.
This patch refactors existing code and add versioning for drivers.
