Code Review
This pull request introduces support for the Discoverable Partitions Specification (DPS) for root partition discovery. It adds a new discoverable-partitions configuration option that, when enabled, omits the root= kernel argument, allowing systemd-gpt-auto-generator to locate the root partition via its DPS type GUID. This feature is enabled by default for systemd-boot and can be configured for GRUB builds that include the Boot Loader Interface (BLI) module. Feedback was provided regarding the use of println! for logging within library code, suggesting a transition to the tracing crate for better consistency with the rest of the codebase.

Right now we default to DPS for composefs + systemd-boot. In Fedora 43+, GRUB has the `bli` module and supports this, so it *can* be used there. Make this configurable (mainly intended for base image builders) so that those with new enough GRUB can flip it on by default. We had a hacky thing here that removed the auto-injected `root=` arg if we detected composefs + sdboot; that can now instead flip on this flag, and then we ensure we don't inject it at all.
