Merge #19069: refactor: replace pointers by references within tx_verify.{h,cpp}

b00266fe0c refactor: replace pointers by references within tx_verify.{h,cpp} (Sebastian Falbesoner)

Pull request description:

  This PR gets rid of another unnecessary use of raw pointers, similar to PR #19053 (see also issue #19062 where useful commands for finding potential candidates are listed) but in the tx verification module.

  For the functions `CalculateSequenceLocks()` and `SequenceLocks()`, the  `prevHeights` vector parameter type is changed to be passed as a reference. Note that there were no checks for null pointers -- if one would pass `nullptr` to one of the functions, the following line would immediately lead to a crash:
