Cleanup: Remove redundant parameter from new Outliner tree building code

Merge branch 'master' into outliner-cpp-refactor

Cleanup: Comments & style improvements for new Outliner C++ code

* Add comments to explain the design ideas better.
* Follow code style guide for class layout.
* Avoid uninitialized value after construction (general good practice).

UI Code Quality: Use C++ data-structures for Outliner object hierarchy building

* Use `blender::Map` over `GHash`
* Use `blender::Vector` over allocated `ListBase *`

Benefits:
* Significantly reduces the amount of heap allocations in large trees (e.g.
from O(n) to O(log(n)), where n is number of objects).
* Higher type safety (no `void *`, virtually no casts).
* More optimized (e.g. small buffer optimization).
* More practicable, const-correct APIs with well-defined exception behavior.

Code generally becomes more readable (less lines of code, less boilerplate,
more logic-focused APIs because of greater language flexibility).

USD importer instancing.

Added basic support for sharing instance prototype meshes.
This allows sharing of mesh geometry for instanceable
prims, but doesn't yet handle converting the point
instancer prim.

UI Code Quality: General refactor of Outliner View Layer display mode creation

* Turn functions into member functions (makes API for a type more obvious &
local, allows implicitly sharing data through member variables, enables order
independend definition of functions, allows more natural language for
function names because of the obvious context).
* Move important variables to classes rather than passing around all the time
(shorter, more task-focused code, localizes important data names).
* Add helper class for adding object children sub-trees (smaller, more focused
units are easier to reason about, have higher coherence, better testability,
can manage own resources easily with RAII).
* Use C++ iterators over C-macros (arguably more readable, less macros is
generally preferred)
* Add doxygen groups (visually emphasizes the coherence of code sections,
provide place for higher level comments on sections).
* Prefer references over pointers for passing by reference (makes clear that
NULL is not a valid value and that the current scope is not the owner).

Progress in using the new IDProperty UI data API

UI Code Quality: Start refactoring Outliner tree creation (using C++)

The Outliner tree creation was very messy and hard to follow. Hardcoded display
type checks are scattered over many places.
This introduces a new abstraction "tree-view" to help constructing and managing
the tree for the different display types (View Layer, Scene, Blender file,
etc.).

Idea is to have an abstract base class to define an interface
(`AbstractTreeView`), and then subclasses with the implementation of each
display type (e.g. `TreeViewViewLayer`, `TreeViewBlenderFile`, etc). The
tree-viewer is kept alive until tree-rebuild as runtime data of the space, so
that further queries based on the display type can be executed (e.g. "does the
view support selection syncing?", "does it support restriction toggle
columns?", etc.).

I may still change the names a bit, not sure yet if "tree-view" is the right
term for this helper.
