erofs: sunset struct erofs_workgroup

`struct erofs_workgroup` was introduced to provide a unique header
for all physically indexed objects.  However, after big pclusters and
shared pclusters are implemented upstream, it seems that all EROFS
encoded data (which requires transformation) can be represented with
`struct z_erofs_pcluster` directly.

Move all members into `struct z_erofs_pcluster` for simplicity.
