935acdcc79 refactor: modernize the implementation of uint256.* (pasta)
Pull request description:
- Constructors of uint256 to utilize Span instead of requiring a std::vector
- converts m_data into a std::array
- Prefers using `WIDTH` instead of `sizeof(m_data)`
- make all the things constexpr
- replace C style functions with c++ equivalents
- memset -> std::fill
This may also be replaced by std::memset, but I think that std::fill is more idiomatic of modern c++ and readable.
- memcpy -> std::copy
Note: In practice, implementations of std::copy avoid multiple assignments and use bulk copy functions such as std::memmove if the value type is TriviallyCopyable and the iterator types satisfy LegacyContiguousIterator. (https://en.cppreference.com/w/cpp/algorithm/copy)
This could also likely be replaced by std::memcpy, but as said above, I believe the using std::copy is the more c++ way to do anything and is almost guaranteed to compile to the same asm
- memcmp -> std::memcmp

In fact, this PR restores behavior that was before bitcoin/bitcoin#22646, and that behavior looks more optimal.
As an outcome, the `contrib/guix/libexec/build.sh` does not spend resources to build binaries which are not a part of the release package.

Also:
- Make DEFAULT_MAX_SIG_CACHE_SIZE into constexpr
DEFAULT_MAX_SIG_CACHE_BYTES to utilize the compile-time integer
arithmetic overflow checking available to constexpr.
- Fix comment (MiB instead of MB) for DEFAULT_MAX_SIG_CACHE_BYTES.
- Pass in max_size_bytes parameter to InitS*Cache(), modify log line to
no longer allude to maxsigcachesize being split evenly between the two
validation caches.
- Fix possible integer truncation and add a comment.
[META] I've kept the integer types as int64_t in order to not introduce
unintended behaviour changes, in the next commit we will make
them size_t.
It is part of the node library. Also, it won't be moved to the kernel
lib, as it will be pruned of ArgsManager.

Overloading sleep_for is not needed, as
* seconds and minutes can be converted to milliseconds by the compiler,
not needing a duration_cast
* std::condition_variable::wait_for will convert milliseconds to the
duration type of the underlying clock
So simply expose the clock.
These files change infrequently, and not much header shuffling is required.
We don't add everything in src/util/ yet, because IWYU makes some
dubious suggestions, which I'm going to follow up with upstream.

This addresses issues like the one in #12467, where some of our compiler flags
end up being dropped during the subconfigure of Univalue. Specifically, we're
still using the compiler-default c++ version rather than forcing c++17.
We can drop the need subconfigure completely in favor of a tighter build
integration, where the sources are listed separately from the build recipes,
so that they may be included directly by upstream projects. This is
similar to the way leveldb build integration works in Core.
Core benefits of this approach include:
- Better caching (for ex. ccache and autoconf)
- No need for a slow subconfigure
- Faster autoconf
- No more missing compile flags
- Compile only the objects needed
There are no benefits to Univalue itself that I can think of. These changes
should be a no-op there, and to downstreams as well until they take advantage
of the new sources.mk.
This also removes the option to use an external univalue to avoid similar ABI
issues with mystery binaries.

Without the fix, the tests immediately abort:
terminate called after throwing an instance of 'std::runtime_error'
what(): locale::facet::_S_create_c_locale name not valid
./qt/test/test_bitcoin-qt: line 2: 116150 Aborted
This adds a unit test that does generic script verification tests,
with positive/negative witnesses/scriptsigs, under various flags.
The test data is large (several MB) so it's stored in the qa-assets
repo.
