Enable gunyah feature for all-aarch64. all-x86_64 inherits all-aarch64
and Gunyah does not support x86_64, so create a new meta-feature,
all-default to support the common features that need to be enabled in
aarch64 and x86_64.
Cherry-pick notes: This commit now adds the "gunyah" feature and is
moved earlier in the series so that changes later in the series can be
properly tested by presubmits.

To support GenieZone (gz) hypervisor as a crosvm hypervisor backend:
- Implement GenieZone hypervisor
- Implement GenieZone’s irqchip
- Create config and feature for GenieZone
- Probe proper hypervisor backend with naive logic
- Inject virtual interrupts
- Bootup guest VM with linux kernel to shell
We still have other todos:
- Integrate with protected VM and pvmfw
- Support multi-core VM
Fixed bugs:
- Replace gz with geniezone in most cases for clarity
- Replace KVM’s ioctl number with GZVM’s ioctl in bindings

We depend on both lazy_static and once_cell, which do basically the same
thing.
The once_cell crate has a few advantages:
- once_cell is on track to be included into libstd.
(https://github.com/rust-lang/rust/issues/74465)
- once_cell doesn't require macro magic.
Replace the uses of lazy_static with their once_cell equivalents so we
don't need to pull in both crates.

Chrome OS does not currently package memoffset-0.6.5 (only 0.6.4), so
building within cros_sdk will fail to find the expected crate. We don't
need any API requirements past what is provided by 0.6, so just request
that. At the same time, upgrade the cros_asyncv2 memoffset from 0.5 to
0.6 so we don't need two separate versions. (The crosvm ebuild was not
requiring a 0.5 version, so this was technically a bug.)

This allows code to create references to traits such as `&dyn Vcpu` for
`&dyn IrqChip`. This also allows keeping such traits inside of opaque
`Box` like wrappers.
To achieve this, trait methods referencing `Self` have an additonal
`where` clause that restricts them to sized types. Associated types are
removed and replaced with their trait equivalents (as parameters) or an
opaque Box (as return values).
To work around certain cases where a concrete type is needed, such as
for KVM based `IrqChip` impls, the `downcast_rs` trait is used to allow
`dynamic_cast` style casting.
The binary size impact of this change is small. For comparison, here is
the size change with this commit:

For now, this crate simply re-exports all of sys_util, but it will
be updated to provide new interfaces when needed. This is the
first step to making crosvm not directly depend on sys_util, so
that we can make the interface changes we need without fear of
negatively affecting (i.e. completely breaking) other usages
within chromeos.
