This commit adds a new `split-debuginfo` option to Cargo compilation profiles which gets forwarded to the `-Csplit-debuginfo` codegen option in rustc. This commit also sets the default, only on macOS, to be `-Csplit-debuginfo=unpacked`. The purpose of this change is to leverage rust-lang/rust#79570 to avoid running `dsymutil` on incremental builds while also preserving a pleasant debugging experience by default. This should lead to much faster incremental build times on macOS since `dsymutil` isn't exactly the speediest tool in the world. This is technically a breaking change in Cargo because we're no longer by-default producing the `*.dSYM` folders on macOS. If those are still desired, however, authors can always run `dsymutil` themselves or otherwise configure `split-debuginfo = 'packed'` in their manifest/profile configuration.
