DNM Fixes for ophyd async types mega merge

[rtuck99]

Fixes breakages in dodal for bluesky/ophyd-async#594

Note this fix depends on #814

TODO

• Unit tests currently failing due to signal names being clobbered on assignment
• Unit tests currently ignored due to assert_configuration() in ophyd async not working for numpy arrays
• panda constructor needs an appropriate URI
• PMACStringFoo devices need to be changed as Signals-inside-signals are no longer permitted
• FluorescenceDetectorControlState needs to be either a str-based StrictEnum with appropriate values

Instructions to reviewer on how to test:

1. Unit tests pass
2. Check the following changes:
   • Usage of StrictEnum/SubsetEnum is appropriate
   • Conversion of signals to numpy array types is appropriate

Checks for reviewer

• Would the PR title make sense to a scientist on a set of release notes
• If a new device has been added does it follow the standards
• If changing the API for a pre-existing device, ensure that any beamlines using this device have updated their Bluesky plans accordingly
• Have the connection tests for the relevant beamline(s) been run via dodal connect ${BEAMLINE}
