tidy: run clang-tidy in quiet mode

[fanquake]

This should cut the amount of output by atleast half.

/opt/homebrew/opt/llvm/bin/clang-tidy --use-color -p=bitcoin bitcoin/src/wallet/test/fuzz/coinselection.cpp
278 warnings generated.
Suppressed 278 warnings (278 in non-user code).
Use -header-filter=.* to display errors from all non-system headers. Use -system-headers to display errors from system headers as well.

becomes

/opt/homebrew/opt/llvm/bin/clang-tidy --use-color -p=/bitcoin -quiet bitcoin/src/wallet/test/fuzz/coinselection.cpp
278 warnings generated.

See https://clang.llvm.org/extra/clang-tidy/.

--quiet
Run clang-tidy in quiet mode. This suppresses
printing statistics about ignored warnings and
warnings treated as errors if the respective
options are specified.

However the run-clang-tidy option is -quiet. See https://github.com/llvm/llvm-project/blob/f28c006a5895fc0e329fe15fead81e37457cb1d1/clang-tools-extra/clang-tidy/tool/run-clang-tidy.py#L244.
