To support cpu sharing, multiple vcpu can run on same pcpu. We need do
necessary vcpu context switch. This patch add below actions in context
switch.
1) fxsave/fxrstor;
2) save/restore MSRs: MSR_IA32_STAR, MSR_IA32_LSTAR,
MSR_IA32_FMASK, MSR_IA32_KERNEL_GS_BASE;
3) switch vmcs.

With cpu sharing enabled, per_cpu vcpu cannot work properly as we might
has multiple vcpus running on one pcpu.
Add a schedule API sched_get_current to get current thread_object on
specific pcpu, also add a vcpu API get_running_vcpu to get corresponding
vcpu of the thread_object.

With cpu sharing enabled, we will map acrn_vcpu to thread_object
in scheduling. From modulization perspective, we'd better hide the
pcpu_id in acrn_vcpu and move it to thread_object.

vcpu thread's stack shouldn't follow reset_vcpu to reset.
There is also a bug here:
while vcpu B thread set vcpu->running to false, other vcpu A thread
will treat the vcpu B is paused while it has not been switch out
completely, then reset_vcpu will reset the vcpu B thread's stack and
corrupt its running context.
This patch will remove the vcpu thread's stack reset from reset_vcpu.
With the change, we need do init_vmcs between vcpu startup address be
settled and scheduled in. And switch_to_idle() is not needed anymore
as S3 thread's stack will not be reset.

Two time related synthetic MSRs are implemented in this patch. Both of
them are partition wide MSR.
- HV_X64_MSR_TIME_REF_COUNT is read only and it is used to return the
partition's reference counter value in 100ns units.
- HV_X64_MSR_REFERENCE_TSC is used to set/get the reference TSC page,
a sequence number, an offset and a multiplier are defined in this
page by hypervisor and guest OS can use them to calculate the
normalized reference time since partition creation, in 100ns units.

Consider the following case when TPR shadow is used with vlapic
basic mode:
1) 2 interrupts are pending in vlapic. INTa's priority > TPR and
INTb's priority <= TPR.
2) TPR threshold is set to zero and INTa is injected to guest.
3) Guest set TPR to the priority of INTa.
4) EOI of INTa. PPR is updated to TPR which equals INTa's priority.
INTb cannot be injected because its priority <= PPR.
5) Guest set TPR to zero. Because TPR threshold is still zero, there is
no TPR threshold vmexit. But since both TPR and ISRV are zero at
this time, the PPR is zero as well. INTb still cannot be injected.
This is a bug.
By adding vcpu_make_request(vlapic->vcpu, ACRN_REQUEST_EVENT) in EOI,
TPR threshold will be updated before vm_resume.
