Merge bitcoin/bitcoin#29484: serialization: replace char-is-int8_t autoconf detection with c++20 concept
ad7584d8b60119ca3717117a1eb6a16d753c5d74 serialization: replace char-is-int8_t autoconf detection with c++20 concept (Cory Fields)
Pull request description:
Doesn't depend on #29263, but it's really only relevant after that one's merged.
This removes the only remaining autoconf macro in our serialization code (after #29263), so it can now be used trivially and safely out-of-tree.
~Our code does not currently contain any concepts, but couldn't find any discussion or docs about avoiding them. I guess we'll see if this blows up our c-i.~
Edit: Ignore this. ajtowns pointed out that we're already using a few concepts.
This was introduced in #13580. Please check my logic on this as I'm unable to test on a SmartOS system. Even better would be a confirmation from someone who can build there.
