Auto merge of #10516 - Alexendoo:split-debuginfo, r=flip1995

Use `split-debuginfo = "unpacked"` for debug builds

On Windows this has no effect as it's unsupported. On macOS the default set by cargo is already unpacked so no effect there either

For Linux it shaves a bit off the rebuild time, for me in the case of a simple `touch` + `cargo build` it goes from 12s to 10s

It saves a good amount of disk space too, on `aarch64-unknown-linux-gnu` it saves 1.2GB for a plain `cargo build`, 3GB when also running `cargo dev` and `cargo test --no-run -F internal`

r? `@flip1995`
