Subject: [PATCH] build-llvm: Reuse the clang-tidy-confusable-chars-gen
 executable

This avoids needing to run the cmake configure for the nested
native build.

This tool (part of clang-tools-extra) is new in LLVM 15.0.0
(and the cmake setting for specifying the binary was backported
after the 15.x branch was made, but before rc1 was tagged).
