hv: multi-arch: abstract some pcpu related interfaces and macros

Browse Source 
The following pcpu related interfaces are moved into common:
- common/cpu.c::start_pcpus
- include/common/cpu.h::get_pcpu_id
- include/common/cpu.h::set_current_pcpu_id
Their arch specific implementations are moved into arch/$(ARCH):
- arch/$(ARCH)/cpu.c::arch_start_pcpu
- include/arch/$(ARCH)/asm/cpu.h::arch_get_pcpu_id
- include/arch/$(ARCH)/asm/cpu.h::arch_set_current_pcpu_id
The following interface is moved into common:
- pcpu_set_current_state (from arch/x86/cpu.c -> common/cpu.c)
The following MACROs are moved into include/common/cpu.h:
- CPU_UP_TIMEOUT
- CPU_DOWN_TIMEOUT
- BSP_CPU_ID
- INVALID_CPU_ID
