[DevASAN] Remove usage of deprecated getPointerTo from AddressSanitizer (#16273)
https://github.com/llvm/llvm-project/pull/113331 deprecates usage of
getPointerTo, llvm::PointerType::get is recommended instead. This
updates AddressSanitizer to use the recommended function in place of the
deprecated one.
