GPKG: do not run vacuum after raster deletion

See my previous commit, for consistency
we do not run VACUUM automatically when
a raster is deleted.

A menu item allows the user to run VACUUM
manually

A possible UX improvement would be to add
a button to the success dialog that
offers the user the option to run VACUUM
after a successful layer deletion.
