This new test class minimally sets up Blender so that it can load blend files and construct a depsgraph without crashing. Note that it hasn't been tested on very complex blend files, so it may still crash when the loaded blend file references/requires uninitialised data structures. The test will certainly crash with Blend files created with Blender older than 2.80, as the versioning code requires space types to be registered. This is normally done by initialising the window manager, which is not done in this test. The WM requires Python to run, which in turn requires that Blender finds the release directory in the same directory that contains the running executable, which is not the case for GTest tests (they are written to `bin/tests/executablename`.
