This is a whitespace-only clang-format change. To verify it, one can run: ```sh (git show | git apply --reverse ) && ( git diff -U0 | ./contrib/devtools/clang-format-diff.py -p1 -i -v ) && git diff HEAD ``` A few minor, non-macro formatting adjustments were made in touched files: * `src/wallet/test/fuzz/crypter.cpp`: Removed a redundant double semicolon * `src/test/fuzz/txorphan.cpp`: Corrected indentation on an `else if` block. * `src/test/fuzz/mini_miner.cpp`: Removed an unnecessary empty line.
