@maflcko: Might introduce `VecFromHex` for tests but I like that this constant is fully compile time.

@paplorinc: I have been trying out exactly that approach quite a bit, but was [warned by maflcko](https://github.com/bitcoin/bitcoin/pull/30377#discussion_r1692989490) that there may be lying dragons among the different serializations of `vector`/`array`/`span`/`Span`. Also had some annoying MSVC compiler errors w

I think it's more rigorous/strict to not use `ParseHex` on both left & right sides of the comparison.

Clang and GCC don't, but MSVC does. :(

Removed in this function in latest push.

I'll meet you half-way with `constexpr auto`. :)

Tried to start switching to `std::byte` after your comment, but it quickly propagated to untouched files.

Attempted to minimize the diff in latest push, but went with `VecFromHex` for string literals and introduced a new `ScriptFromHexStr` for the 2 runtime validated call sites.

Weird, actually works for me on same clang version as @stickies-v, but under Linux:
```
$ clang --version
clang version 17.0.6
Target: x86_64-unknown-linux-gnu
```
Maybe it's the standard library that is somehow different (missing some `constexpr`)?

How come? `ParseHex("")` returns `0` as verified by **util_tests.cpp**. Besides that, I think it's not really what we are testing in this file.

Updated with slightly different string in latest push and removed comment about consistency above as well.

```C++
throw "Only lowercase hex digits are allowed, for consistency";

> This instead seems to be a reversion to prior behaviour to facilitate something CMake related. I'm curious why this has only become an issue now, given we've already got the tests in CMake? Or is this something that was missing and is being ported now?

I had some concerns while documenting CTest behaviour in https://github.com/hebasto/bitcoin/pull/329.

```
* @warning Unlike VecFromHex which returns a vector, the returned array may use

Code review ACK 65bc6dcd573fe74d2ce175466c30ed830d17f0fc. Looks good, thanks for working on this, and I think this will avoid the need to add the ParseHex suppression in #30415. Left a few comments but nothing critical.

Might be worth mentioning this change in commit message or saying it has other test cleanups.
