fac5c373006a9e4bcbb56843bb85f1aca4d87599 scripted-diff: Sort test includes (MarcoFalke)
Pull request description:
When writing tests, often includes need to be added or removed. Currently the list of includes is not sorted, so developers that write tests and have `clang-format` installed will either have an unrelated change (sorting) included in their commit or they will have to manually undo the sort.
This pull preempts both issues by just sorting all includes in one commit.
Please be aware that this is **NOT** a change to policy to enforce clang-format or any other developer guideline or process. Developers are free to use whatever tool they want, see also #18651.
Edit: Also includes a commit to bump the copyright headers, so that the touched files don't need to be touched again for that.

fa8a99258947a9ee3749fa472180542920cd471c Work around memory-aliasing in descriptor ParsePubkey (MarcoFalke)
Pull request description:
While this is not undefined behaviour, the memory aliasing trick is confusing when reading the code. Having `a.size()==0` and then access `a[0]` works in this particular case, but should probably be avoided to harden the code for the future.

9272d70 Support serializing Span<unsigned char> and use that instead of FLATDATA (Pieter Wuille)
833bc08 Add Slice: a (pointer, size) array view that acts like a container (Pieter Wuille)
Pull request description:
Introduce a new data type `Span`, which is an encapsulated pointer + size (like C++20's `std::span` or LevelDB's `Slice`), and represents a view to a sequence of objects laid out continuously in memory.
The immediate use case is replacing the remaining `FLATDATA` invocations. Instead of those, we support serializing/deserializing unsigned char `Span`s (treating them as arrays).
A longer term goal for `Span`s is making the script execution operate on them rather than on `CScript` itself. This will allow separate storage mechanisms for scripts.
