VcpuRunHandle was only used to signal immediate_exit on unix platforms;
it was unnecessary on Windows. It is replaced with a new
VcpuSignalHandle abstraction that is only implemented for cfg(unix).
This commit moves the thread local storage out of hypervisor and into
the unix/vcpu.rs code; it does not need to be duplicated in each
hypervisor backend.

Remove the fallback path that supported old KVM versions without
KVM_CAP_IMMEDIATE_EXIT, which has been available since Linux 4.11 /
commit 460df4c1fc7c ("KVM: race-free exit from KVM_RUN without POSIX
signals").
This also removes the need for the Vcpu::set_signal_mask() function, so
it is removed from all hypervisors.

The KVM docs say
If setting an MSR fails, ..., it stops processing the MSR list and
returns the number of MSRs that have been set successfully.
So, a return value of zero really means the operation completely failed.

Pick an even more invalid MSR index so the MSR will actually fail to be

These tests require kvm to pass and are not suitable for a unit
test.
In order to move the test, KvmVm::create_vcpu had to be renamed
to prevent conflicts with the trait function VcpuX86_64::create_vcpu,
implemented for the same type.
The aarch64 variant does not actually run in CI since the tests
do not pass in the emulated aarch64 environment. So the
DO_NOT_RUN_AARCH64 flag remains.

We are going to need to start passing a new arch-dependent configuration
parameter to KvmVm::new in addition to protection_type. Since we can't
[cfg] a function argument, and to avoid churning the tests the next time
we need another argument, let's create a hypervisor::Config struct and
start passing protection_type that way.

crosvm is switching the import style to use one import per line.
While more verbose, this will greatly reduce the occurence of merge
conflicts going forward.
Note: This is using a nightly feature of rustfmt. So it's a one-off
re-format only. We are considering adding a nightly toolchain to
enable the feature permanently.

Add methods for making RunnableVcpus, requesting vmexits on a vcpu,
injecting interrupts, and setting I/O data. This code is unchanged
from the kvm crate.
A new Vcpu::handle_io_events method delivers pending IO events. This is
for hypervisors that handle IO events in userspace. On KVM it's a
no-op.
Delete integration tests, which were for showing how the hypervisor
traits fit together.
