Add bending in y-direction to Velo-SciFi matching

Jiahui Zhuo requested to merge jzhuo_FixMatchingAsym into 2024-patches

Address the asymmetry issue described in #537 (comment 7904442)

Adding the Y direction bending parametrization back to HLT1 matching, using the same input variables as HTL2. Reference in HLT2: https://gitlab.cern.ch/lhcb/Rec/-/blob/2024-patches/Pr/PrAlgorithms/src/PrMatchNN.cpp#L337

Remove the non-sense correction in VELO extrapolation

Before the fix: image

After the fix: image

The bending parametrization is computed with 2024-expected MC, the validation plots are obtained with dumped mep (run=291817)
