Removing CUF runtime dependency with llvm::EnableABIBreakingChecks (#111200)

getMemType happens to only be used in CufOpConversion.cpp. So, moving it
here for now. If it needs to be shared with the runtime, then care
should be taken in not bringing the include `#include
"flang/Optimizer/Dialect/CUF/Attributes/CUFAttr.h"` which introduces the
dependency with llvm::EnableABIBreakingChecks
