[BUGFIX] Allow Extbase HashService retrieval via GeneralUtility::makeInstance()

With the deprecation of extbase `HashService`, the new core
`HashService` was injected to extbase `HashService` using constructor
DI. Instantiation of extbase `HashService` however does not work,
because the service is defined by a service provider and the
required constructor argument is missing.

This change makes the extbase `HashService` injectable by DI
again by removing it from the service provider definition and
by defining it as public using `Autoconfigure` attribute.
