Disable from-text stub generation for i18n.module.intra.core.api

i18n.module.intra.core.api depends on i18n.module.public.api
for from-text stub generation, as the generated stubs contain APIs that
are not included in the api signature file generated from this module.
However, setting i18n.module.public.api as a dependency of
i18n.module.intra.core.api leads to circular dependency and
requires further bootstrapping to resolve the issue.

This change does not lead to any user-facing changes, as
i18n.module.intra.core.api is currently being built from-source by
default.
