refactor: export fieldComponents.js

* fieldComponents contains some helpers that are used by field
components in other Invenio modules such as `invenio-app-rdm` and
`invenio-vocabularies`. In the future, it may also be used by custom
field implementors.

* This commit exports it at the top level of the package
