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.

We only need to do this for x86 since MSHV does not have aarch64 support
yet. This reduces unnecessary code churn.

Combined the `GicDevice` struct in `arch` crate and the `Gic` struct in
`devices` crate.
After moving the KVM specific code for GIC in `arch`, a very thin wapper
layer `GicDevice` was left in `arch` crate. It is easy to combine it
with the `Gic` in `devices` crate.

`GicDevice` trait was defined for the common part of GicV3 and ITS.
Now that the standalone GicV3 do not exist, `GicDevice` is not needed.

Why combine:
- GicV3 is not required alone
- GicV3 and GicV3Its has separate snapshot/pause code. But the code of
GicV3 was never used.
- Reduce the code complexity of GIC related traits and structs.

There is no need to include serde_derive separately,
as it can be specified as serde feature instead.

This variable name is residual from when these functions acted directly
on the vCPU fd rather than the hypervisor wrapper.

EDK2 execution requires a flash device at address 0.
The new added device is not a fully functional flash. It doesn't
implement any spec of a flash device. Instead, a piece of memory is used
to simulate the flash simply.

Size of `memory` node in FDT was reduced by 4MiB. Now it is returned.
In memory regions, a `Ram` region of 4MiB was created at address 0. Now
it is removed.

Rust 2021 edition has a few improvements over the 2018 edition. Migrate
the project to 2021 edition by following recommended migration steps.
Luckily, the code itself doesn't require fixing.
Bump MSRV to 1.56 as it is required by the 2021 edition. Also fix the
clap build dependency to make Cloud Hypervisor build again.

This is a refactoring commit to simplify source code.
Removed some functions that only return a layout const.

Based on latest QEMU patches from branch tdx-qemu-2022.03.29-v7.0.0-rc1
we don't need EFI_RESOURCE_ATTRIBUTE_ENCRYPTED as part of the attributes
we must enable with EFI_RESOURCE_SYSTEM_MEMORY and
EFI_RESOURCE_MEMORY_RESERVED resource types.
