Merge #18675: tests: Don't initialize PrecomputedTransactionData in txvalidationcache tests

3718ae2ef8dd2559e435bf8d7f5ed5217611ce81 [tests] Don't initialize PrecomputedTransactionData in txvalidationcache tests (John Newbery)

Pull request description:

  PrecomputedTransactionData is initialized inside CheckInputScripts(). No need to pre-initialize it before calling into CheckInputScripts().

  Normally, I wouldn't bother, but we're making changes to `PrecomputedTransactionData` in #17977 which would break these tests without removing these constructions. Might as well get these changes out of the way here.
