⬆️ update `mqt-core`

[burgholzer]

Description

This PR was triggered by the failures in #349 and its purpose is to better isolate the changes into separate PRs.

• cda-tum/mqt-core#515

has dropped the submodules in mqt-core and replaced them with FetchContent. As such, the googletest test dependency is no longer available at its typical location. Consequently, this PR now also uses FetchContent to get googletest. In a future PR, this will most likely be extended to the mqt-core submodule as well.

This should unblock #349.
