Issue #8488 (#8490)

Summary of Changes
This pull request adds an entry for Distances in the vbosName enum. The
new entry designates the buffer that contains the distance values for
vertices or facets. This change ensures that distances can be managed
consistently with other vertex data, such as coordinates, normals, and
colors.

Release Management
Affected package(s): GraphicsView (or any package dealing with vertex
buffer objects, depending on where this enum is used)
Issue(s) solved (if any):
