Pull request description:

  Missing `bitcoin-config.h` includes are problematic, because the build could silently pass, but produce an unintended result. For example, a slower fallback algorithm could be picked, even though `bitcoin-config.h` indicates that a faster feature is available and should be used.

  As the build succeeds silently, this problem is not possible to detect with iwyu.

  Thus, fix this by using a linter based on grepping the source code.

    ACK fa58ae74ea, tested on Ubuntu 23.10 -- it catches bugs properly. I didn't review rust code changes.
