Add this vcpu_affinity[] for each VM to indicate the assignment policy.
With it, pcpu_bitmap is not needed, so remove it from vm_config.
Instead, vcpu_affinity is a must for each VM.
This patch also add some sanitize check of vcpu_affinity[]. Here are
some rules:
1) only one bit can be set for each vcpu_affinity of vcpu.
2) two vcpus in same VM cannot be set with same vcpu_affinity.
3) vcpu_affinity cannot be set to the pcpu which used by pre-launched VM.
v4: config SDC with CONFIG_MAX_KATA_VM_NUM
v5: config SDC with CONFIG_MAX_PCPU_NUM

There is plan that define each VM configuration statically in HV and let
DM just do VM creating and destroying. So DM need get vcpu_num
information when VM creating.
This patch return the vcpu_num via the API param. And also initial the
VMs' cpu_num for existing scenarios.

The name NORMAL_VM does not clearly reflect the attribute that these VMs

that these VMs are launched "later" by one of the VMs launched by ACRN.

Currently VM id of NORMAL_VM is allocated dymatically, we need to make
VM id statically for FuSa compliance.
This patch will pre-configure UUID for all VMs, then NORMAL_VM could
get its VM id/configuration from vm_configs array by indexing the UUID.
If UUID collisions is found in vm configs array, HV will refuse to
load the VM;

Previously we use unified vm_config.c for all scenarios and use MACROs
for each configuration items, then the initialization of vm_configs[]
becomes more complicated when definition of MACROs increase, so change
the coding style that all configurable items could be explicitly shown in
vm_configuration.c to make code more readable.

After using get_vm_from_vmid(), vm pointer is always not NULL. But there are still many NULL pointer checks.
This commit replaced the NULL vm pointer check with a validation check which checks the vm status.
In addition, NULL check for pointer returned by get_sos_vm() and get_vm_config() is removed.

Previously the vm_configs[] is defined separately for sharing mode and
partition mode, but the concept of hypervisor mode will be removed. Instead
we will introduce scenario Kconfig for hypervisor to load different vm
configurations.
SDC(Software Defined Cockpit) is a typical scenario that ACRN supported
so we introduce this scenario for previously sharing mode and move its
configurations to scenarios/sdc folder. The configuration could be used
for all boards reference.
