> dso__demangle_sym() is the only place that implements demangling logic

> parsing and buffer growth into rust_demangle_sym(), with the same
> signature as the other three.

> A Rust name that fails to demangle now falls through to the other
> demanglers, matching how the other demanglers chain into each other.
> A v0 name can't be misread by any of them, since none accepts its "_R"
> prefix. A legacy name can only fail here on allocation failure or
> hitting the output bound, neither of which is language-specific.
