Remove per-event warnings:
SGInputLoader 18 0 WARNING unable to find proxy for ( 'xAOD::VertexContainer' , 'StoreGateSvc+GSFConversionVertices' )
from an unneeded egamma tool (ATR-20537)
Set - didn't manage to get this due to interference from the fixes in 32601. But this is still good to merge as is.
failIfNoProxy=True in main trigger CI test,
test_trig_data_v1Dev_build.py to stop these messages in the future (ATR-20535)
Change the data dependency checker to run on MC where the problems persist.
