acrn-config: change names for vcpu_affinity[] related items

Browse Source 
hypervisor is replacing vm_configs[].vcpu_affinity[] array with
cpu_affinity_bitmap, the meaning of which has some changes as well.

This patch changes the names in generated vm_configuration.c:
-.vcpu_affinity = VMx_CONFIG_VCPU_AFFINITY,
+.cpu_affinity_bitmap = VMx_CONFIG_CPU_AFFINITY,

Changes in vm_configuration.h:
-#define  VMx_CONFIG_VCPU_AFFINITY {AFFINITY_CPU(xU), AFFINITY_CPU(xU)}
+#define  VMx_CONFIG_CPU_AFFINITY  (AFFINITY_CPU(xU) | AFFINITY_CPU(xU))

Also don't generate default assignment of vcpu_num in vm_configuration.c,
because now hypervisor can easily calculate it from cpu_affinity_bitmap.

Accordingly, in the scenario xml files, tag "vcpu_affinity" is changed
to "cpu_affinity".
