[llvm][ELF][build attributes] Change StringRef to std::string for BuildAttributeSubSection::Name (#135625)

Browse Source 
BuildAttributeSubSection::Name must be a std::string instead of
StringRef because it may be assigned from non-persistent memory.
StringRef is non-owning and unsafe in this context. This change ensures
the subsection name owns its memory, preventing use-after-free or
dangling references.

Context: Work in progress in PR #131990.
