Improve low-mass dielectron lines

• Remove "Noip" from the dielectron lines since, after splitting the line up to allow more targetted pre-scaling, some sub-lines end up having an implicit ip cut.
• Cut on track IPchi2 not vertex IPchi2 (which is just pointing-angle)
• Remove the prompt_vertex_evaluator dependence of the code to put the selection in one place

(this will need Moore!2626 (merged) to be merged at the 'same' time given the change in HLT1 line names here that that MR then filters on)
