ClangTools: Remove dependency to libclang and custom clang binary

Browse Source 
Before this change, we've invoked a custom clang binary that had clazy
statically compiled into it. The invocation also ensured that the
diagnostics were serialized to a file, so that libclang could be used
afterwards to read them.

As the clazy-standalone executable supports exporting diagnostics to a
YAML file now (just as clang-tidy) and Qt Creator ships it already, rely
on that executable alone instead of the clang/libclang combo.

While we do not depend on any clang header or library at build-time now,
the CompilerOptionsBuilder constructor still needs the CLANG_VERSION and
CLANG_RESOURCE_DIR pieces from llvm-config. This dependency should be
removed as next.
