samples: rust: rust_driver_pci: use HRT lifetime for Bar

Convert the sample driver to SampleDriver<'bound>, taking advantage of
the lifetime-parameterized Driver trait.

The driver struct holds &'bound pci::Device directly instead of
ARef<pci::Device>, and pci::Bar<'bound> directly instead of
Devres<pci::Bar>. This removes PinnedDrop, pin_init_scope, and runtime
revocation checks on BAR access.
