Adding hypervisor crate to abstract out Kvm implementation This is a separate hypervisor crate for interacting with Kvm in an abstract manner. The intention is to not leak the internals of kvm with its specific calls in various places in the codebase. Currently, this just creates an initial structure for adding various implementations over time. In addition, a SafeDescriptor class is added, that wraps a raw file descriptor safely, without needing to wrap it in the rust file class. The intention is to use this for non file raw descriptors.

data_model = { path = "../common/data_model" }
make hypervisor traits object safe 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: armv7a -0.49% (-9 kiB) aarch64 -0.17% (-3 kiB) x86_64 +1.77% (+40 KiB) BUG=None TEST=build_test Cq-Depend: chromium:2466660 Change-Id: I1a408734832d2971ea2979c1bc64b2ffe051b02d Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/crosvm/+/2439298 Reviewed-by: Zach Reizner <zachr@chromium.org> Tested-by: Zach Reizner <zachr@chromium.org> Tested-by: kokoro <noreply+kokoro@google.com> Commit-Queue: Zach Reizner <zachr@chromium.org>

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.
