[TASK] Replace GeneralUtility::hmac usage in ext:core

With #102761, the new `HashService` has been introduced to ensure
that HMAC generation will always use an additional secret. As a
follow-up patch, `GeneralUtility::hmac` will be deprecated when all
usages in the core have been replaced with the new `HashService`.

With this change, usages of `GeneralUtility::hmac` in ext:core
are replaced by the new HashService.
