Add them liberally, though perhaps not as liberally as in hw/char/pl011/src/lib.rs. In particular, enabling entire groups can be problematic because of bitrot when new links are added in the future. For Clippy, this is actually a feature that is only present in Cargo 1.74.0 but, since we are not using Cargo to *build* QEMU, only developers will need a new-enough cargo and only to run tools such as clippy. The requirement does not apply to distros that are building QEMU.
