fanquake 54646167db Merge #18388: Make VerifyWitnessProgram use a Span stack
2b0fcff7f2 Make VerifyWitnessProgram use a Span stack (Pieter Wuille)

Pull request description:

  Here is a follow-up to #18002, again with the goal of simplifying (potential) BIP341 code.

  Instead of passing a begin and end iterator of the initial stack to `ExecuteWitnessScript`, they are turned into a `Span<const valtype>`, representing a span of `valtype`s in memory. This allows `VerifyWitnessProgram` to operate on that span directly, instead of juggling iterators around (which would be exacerbated by #17977 if trying to avoid copying the stack).
