chore: Enable v0 symbol mangling (#2985)

Piotr Osiewicz created 2 years ago

https://github.com/rust-lang/rust/issues/60705
Due to modification of .cargo/config.toml your `cargo build` should pick
this change up automatically. Use `legacy` instead of `v0` if you find
yourself in need of old mangling scheme for whatever reason
Release Notes:

- Improved precision of backtraces in application crashes
