clang-tidy: Make .clang-tidy a build-time dependency
Currently a change to the clang-tidy configuration remains unnoticed for
incremental builds in the way that it won't trigger a rebuild. This can be
considered a missing dependency that this patch fixes by introducing a
compile time definition (-DCLANG_TIDY_SHA1) that triggers a rebuild upon
change. Currently this only applies to the target CMakeLib.
