Previous `Vaia` implementation uses types as it is, thus the property
string generated for fdt setup requires additional type conversion.
Change the types used in the methods of `Vaia` trait to provide a
concise fdt setup process.

Asserting on .is_ok()/.is_err() leads to hard to debug failures (as if
the test fails, it will only say "assertion failed: false". We replace
these with `.unwrap()`, which also prints the exact error variant that
was unexpectedly encountered (we can to this these days thanks to
efforts to implement Display and Debug for our error types). If the
assert!((...).is_ok()) was followed by an .unwrap() anyway, we just drop
the assert.
Inspired by and quoted from @roypat.

Historically the Cloud Hypervisor coding style has been to ensure that
all imports are ordered and placed in a single group. Unfortunately
cargo fmt has no support for ensuring that all imports are in a single
group so if whitespace lines were added as part of the import statements
then they would only be odered correctly in the group.
By adopting "group_imports="StdExternalCrate" we can enforce a style
where imports are placed in at most three groups for std, external
crates and the crate itself. Choosing a style enforceable by the tooling
reduces the reviewer burden.

Assume rax is 0xfee003e0 and the displacement is negative 0x60. The effective

On x86-64, when the underlying hypervisor platform is KVM, no
instruction emulator is necessary. KVM handles instruction boundaries
internally.
This change allows to skip the iced-x86 dependency on KVM, improving
build times, prunes the dependency graph and reduces network traffic
during the initial build.
For Hyper-V, the emulator is still necessary on x86-64, so nothing
changes there.

This requires making get/set_lapic_reg part of the type.
For the moment we cannot provide a default variant for the new type,
because picking one will be wrong for the other hypervisor, so I just
drop the test cases that requires LapicState::default().
