Switch to vectorised track combiner in HLT1 lines

Brief summary: Replace CombineTracks with CombineTracksSIMD

Detailed changes:

• Drop BPVIPCHI2STATE functor
• Drop dumping functionality of CombineTracks, given that DumpContainer exists this is a minimal loss in functionality. Drop some "debug" versions of lines that used this feature (but did not run by default).
• Add POD functor wrapper in DumpContainer wrappers
• Change logic in the SelReports configuration to support the new v2::Composites output
• Explicitly specify relevant mass hypotheses in all 2-track lines, this is now a property of the combiner instead of being set by the functors that apply the selection.

Should be tested with LHCb!2650 (merged) and Rec!2134 (merged).
