Remove hacked Prefect functions to upstream Prefect

What would you like to report?

In #2460 and #2462 by @zulissimeta, we have added some routines to nicely resolve Prefect futures. However, this involved some copying of boilerplate code that should really be submitted to the upstream Prefect library. While somewhat annoying, this should be taken care of ASAP to prevent breakages.

Here are the functions to take care of: https://github.com/Quantum-Accelerators/quacc/blob/main/src/quacc/wflow_tools/prefect_utils.py
