  [Remarks] YAMLRemarkSerializer: Fix StringRef out-of-bounds read (#159759)

YAML IO `mapRequired` expects a null-terminated `const char *` Key, so
we can't legally pass a StringRef to it. We should add StringRef Key
support to YAML IO, but for now just copy the key into a correctly
null-terminated string.
