Docs: remove redundant @package tags

`@package` tags are an arcane manner to group related files as belonging to one project.

For projects using namespaces, the current recommendation is to only have `@package` tags when they have supplemental information to the namespace.

That is only in a very limited way the case in VIPCS, so I'm proposing to remove the `@package` tags from the VIPCS class docblocks, though leaving them for now in the file docblocks.

At the very least, this removed duplicate information for which there is no reason for the duplication.

Includes cleaning up (normalizing) the tag description alignments in the class docblocks.

:point_right: reviewing with whitespace changes ignored should make it easier to see that the only real change is the removal of the package tags.
