Cleanup: Select sync from outliner

Move the condition to check if selection syncing is enabled to inside
the syncing function rather than before each time it is called.

Fix: Selection syncing for outliner operators

A few outliner operators that modify selection were not tagging for a
selection sync which led to selection inconsistencies. This adds syncing
for the following operators:
* Duplicating and deleting collections
* Selecting/deselecting collection contents
* Drag and drop
* Object select, deselect, delete, and delete hierarchy

BLI: add LinearAllocator

This allocator is useful when it is necessary to allocate many small elements.

BLI: improve StringRef.copy

BLI: add DefaultHash specializations for StringRef and StringRefNull

BLI: Implement StringMap.add and StringMap.add_or_modify

UI: Move Scene Statistics to the 3D Viewport

Removes statistics from footer and to an (optional) overlay in 3DView.

Fix T69753 Instanced Metaballs not rendering but showing up in Viewport

This hides the original metaballs when they are used in
duplifaces/-verts instancing, and still shows the instanced metaballs.

The visibility of the original metaballs is now determined by the
visibility of the instancer. I'm not too thrilled about this, but at
least it gives users the ability to show/hide the metaballs for
viewport/render.

Tests: use explicit Python to run unit tests

CentOS on the buildbot still runs Python 3.6, which is also used for the
unit tests. This means that the tests can't use language features that
are available to Blender itself. And testing with a different version of
Python than will be used by the actual code seems like a bad idea to me.

This commit adds `TEST_PYTHON_EXECUTABLE` as advanced CMake option. This
will allow us to set a specific Python executable when we need it. When
not set, a platform-specific default will be used:

- On Windows, the `python?.exe` from the installation directory. This is
just like before this patch, except that this patch adds the
overridability.
- On macOS/Linux, the `${PYTHON_EXECUTABLE}` as found by CMake.

Every platform should now have a value (configured by the user or
detected by CMake) for `TEST_PYTHON_EXE`, so there is no need to allow
running without. This also removes the need to have some Python files
marked as executable.

If `TEST_PYTHON_EXE` is not user-configured, and thus the above default
is used, a status message is logged by CMake. I've seen this a lot in
other projects, and I like that it shows which values are auto-detected.
However, it's not common in Blender, so if we want we can either remove
it now, or remove it after the buildbot has been set up correctly.

Defaults: Change default axes for Track To constraint

The main use-case for the Track To constraint is camera tracking, so
this sets up a better default for this. That is, track to -Z with Y up.

Agreed on internally with Pablo Vazquez and William Reynish. Should
there be a reason to revert this, that would be fine compatibility-wise.

Defaults: Reduce near-clipping in factory settings

For newly opened 3D Views, the default would actually be 0.01m. But the
code to update the default for all existing 3D Views in the
startup.blend was missing. So the defaults were out-of-sync.

0.01m is the more reasonable default as agreed on by the UI team.

Alembic: added camera writer

Alembic: support writing metaballs

This commit also introduces a change in how Alembic C++ objects are created.
This no longer happens in the constructor, but is done in a different
function that's only called when `writer->is_supported(context)` returns
`true`.

Alembic: fixed subsurf modifiers not being re-enabled after export

Alembic: much cleaner way to get the parent Alembic object

Rather than juggling pointers around, the iterator's writer map is used.
This makes it possible to construct the Alembic object in the writer's
constructor, and makes the writers much simpler to understand.

Alembic: CMake cleanup

No functional changes.
