The `Eraser Hard` and `Eraser Point` were almost identical in behavior.
* `Eraser Hard` was set to `Disslove` making the edges soft, not hard.
Now this is set to `Point` mode to delete the points and make actual
hard edges.
* The `Eraser Point` is obsolete and was removed.
This change moves the tests data files and publish folder of assets
repository to the main blender.git repository as LFS files.
The goal of this change is to eliminate toil of modifying tests,
cherry-picking changes to LFS branches, adding tests as part of a
PR which brings new features or fixes.
More detailed explanation and conversation can be found in the
design task.
