Clarin9/Restrict main search page to items only

The main /search page previously returned all DSpace object types (items,
collections and communities), matching the backend `default` discovery
configuration. In v7 only items were shown there.

Add a reusable `forcedDsoTypes` input to the (themed) SearchComponent that
forces the given DSpaceObject types onto every search request the component
makes, and set it to items only on the main search page. Community and
collection results are therefore hidden from /search, while other search
pages (MyDSpace, admin, browse, scoped configuration searches) are untouched.

Clearing SearchPageComponent.forcedDsoTypes restores the previous behaviour,
and the input can be reused to expose this as a facet/config later.
