  [config] Remove vestigial LLVM_VERSION_INFO

This has been superseded by the llvm/Support/VCSRevision.h header. So
far as I can tell, nothing in the CMake build sets LLVM_VERSION_INFO. It
was always undefined, and the ifdefs using it were dead. However, CMake
is very flexible, so it's possible that I missed some ways to set this
variable. One could, for example, probably pass -DLLVM_VERSION_INFO=x on
the command line and get that through to configure_file, or set the
variable in an obscure way (`set(${proj}_VERSION_INFO "x")`). I'm
reasonably confident that isn't happening, but I'd like a second
opinion.

Update the Bazel and gn builds accordingly.
