Demangled Rust identifiers under the `legacy` name mangling scheme rely on a hash to disambiguate items with the same name, such as different monomorphisations of the same function or different closures’ `call_once` methods. In the `v0` mangling scheme, this is no longer a problem. However, configuring the demangler to show hashes in `legacy` names will include crate-id hashes in `v0` names, which are [mostly unneeded](https://rust-lang.github.io/rfcs/2603-rust-symbol-name-mangling-v0.html#appendix-a---suggested-demangling). This PR introduces a new checkbox *Options...* → *Verbose demangling* that lets the user select if they want to include disambiguating hashes in demangled identifiers. This checkbox is only shown for compilers that support verbose demangling, and deactivated when the *Demangle identifiers* checkbox is unchecked. Resolves #1754. Resolves #6255.
