The code of the stable branch diverges from the main branch, so we
can't directly backport the corresponding commit to fix the clippy
issues.

MSHV does not require to ensure MMIO/PIO exits complete
before pausing. This patch makes sure the above requirement
by checking the hypervisor type run-time.
Fixes#5037

(cherry picked from commit 4e3bc20f2ceac9ea3861b76512375cc5f295dc97)
TDX functionality is not currently available on MSHV but we should not
preclude building a binary that can run on both.

The latest kvm-ioctls contains a breaking change to its API. Now Arm's
get/set_one_reg use u128 instead of u64.

Use VgicConfig to initialize Vgic.
Use Gic::create_default_config everywhere so we don't always recompute
redist/msi registers.
Add a helper create_test_vgic_config for tests in hypervisor crate.

VgicConfig structure will be used for initializing the Vgic.
Gic::create_default_config will be used everywhere we currently compute
redist/msi registers.

Set the maximum number of HW breakpoints according to the value returned
from `Hypervisor::get_guest_debug_hw_bps()`.

Added `Hypervisor::get_guest_debug_hw_bps()` for fetching the number of
supported hardware breakpoints.

The field can be set directly.
This eliminates one place where dyn Device is used outside of KVM
aarch64 code.

The code was moved from the vmm crate to the hypervisor crate. After the
move it is trivially obvious that it only works with KVM. Use concrete
types where possible.
This allows us to drop create_device from the Vm trait.
No functional change intended.

The original code uses kvm_device_attr directly outside of the
hyeprvisor crate. That leaks hypervisor details.
No functional change intended.

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().

CpuId is an alias type for the flexible array structure type over
CpuIdEntry. The type itself and the type of the element in the array
portion are tied to the underlying hypervisor.
Switch to using CpuIdEntry slice or vector directly. The construction of
CpuId type is left to hypervisors.
This allows us to decouple CpuIdEntry from hypervisors more easily.
No functional change intended.
