remove: remove stats/base/dvariancech from namespace

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

BREAKING CHANGE: remove `stats/base/dvariancech`

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

Ref: #4797
