remove: remove stats/base/sdsmean from namespace

This commit removes the `sdsmean` symbol from the `@stdlib/stats/base` namespace due to a package migration.

BREAKING CHANGE: remove `stats/base/sdsmean`

To migrate, users should access the same symbol via the `@stdlib/stats/strided/sdsmean` namespace.

Ref: #4797
