Ophyd async support in configure_base

[thopkins32]

Example failure:

import nslsii
from ophyd_async.epics.motor import Motor
from ophyd_async.core import init_devices

nslsii.configure_base(...)
with init_devices():
    m = Motor("<pv-prefix>", name="m")

This is also causing issues with autoawait_in_bluesky_event_loop

import nslsii

nslsii.configure_base(...)
# Overwrite the run engine
RE = RunEngine()
autoawait_in_bluesky_event_loop()

The only way it works is if I overwrite the RunEngine
