This cached field was only accessed precisely once, so the getter might
as well compute it instead. While we're at it, merge the getting with
the free-standing computation function.

Just make this a method on `Aarch64RegisterVec`, and make it return
`Option`, because there was only a single error case, and the error
message was additionall never displayed because the only call site
ignores errors beyond acknowledging that they happened.

Almost all the free functions in arch::arch64::vcpu were just taking a
vcpu reference as a first parameter (in some form). So just turn these
into methods implemented on KvmVcpu that take &self.

Remove some more .map_err() noise in the mmio device registration code
in builder.rs by using #[from] and returning more specialized error
types.
