Support J and K beamline prefixes

[callumforrester]

Attempts to integrate I13-1 were hampered by its PVs having BL13J-... prefixes. Ideally we should be able to configure dodal so device_instantiation can pick this up from I13-1.

Since I04-1 and I20-1 are already in dodal and their PVs resolve to BL04I-... and BL20I-..., I assume those are the actual prefixes for those beamlines. I will check when able.

Acceptance Criteria

• We can put some configuration in the i13_1 dodal module such that device_instantiation automatically inserts BL13J prefixes at the front of PV names
• We can remove the bl_prefix=False argument currently present for all devices
• There are regression tests to ensure we do not break existing beamlines

Hmm... i20-1 and i04-1 are currently also broken because of this. It did work at one point and it's why BeamlinePrefix allows you to specify a suffix but clearly there was a regression. Running dodal connect i20-1 confirms that it's broken but annoyingly dodal connect i04-1 looks like it works because the hardware in dodal so far is the same for i04 and i04-1
