  [cmake] Warn if LLVM_PROFDATA_FILE was specified but wasn't found (#139882)

Ideally we should perhaps even error out here; if the user requested
building with profiling info, but that profile wasn't found, it seems
like the build configuration is subtly broken, and I would expect the
user to want to know about it. But that may be a too disruptive change,
as users may very well rely on being able to build things in such a
setup anyway thanks to Hyrum's Law.

To make things clearer, at least print a warning in this case.
