This fixes the valid VM config unit tests, which would otherwise fail
to deserialize their expected JSON config due to the missing "gdb" field.

The vsock backend may be shared between threads, so the type `B` in
`Vsock` should be `VsockBackend` and `Sync`.
Considering that `api_receiver` and `gdb_receiver` are only used in vmm
threads, the `Arc` can be replaced by `Rc`.

This gives users the chance to reduce the number of dependencies
included, which is generally good practice and also reduces code size.
Furthermore, `io_uring` specifically is a strong contender for something
one may wish to disable due to the syscall API's many security issues[1]

test_cpu_affinity needs the number of host CPUs. Since it is possible
for the host to have more than 255 CPUs; increase the size of the
datatype used for parsing the string to accomodate this.

Add integration test for pvpanic, by two methods:
- the vendor id and device id of pci device in guest
- triggering a guest panic and check event-monitor.

This reverts commit efb579b224.
This PR was mistakenly merged due to the confusion around nightly

and fuzz workspace together.

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.
