HV: Added Initial support for SEP/SOCWATCH profiling

Browse Source 
This patch adds support to sep/socwatch profiling
     Adds 2 new files include/arch/x86/profiling.h and arch/x86/profiling.c
     which contains most of the implementation for profiling,most of the functions
     in profiling.c have dummy implementation and will be implemented in next patches

     a. cpu.c, Initial profiling setup is done as part of bsp_boot_post
  and cpu_secondary_post flow
     b. vmcall.c, New ioctl is added for performing profiling related
  operations in vmcall_vmexit_handler
	ioctl - HC_PROFILING_OPS
        function - hcall_profiling_ops()
     c. common/hypercall.c, hcall_profiling_ops() implementation.
     d. hv_main.c, In vcpu_thread calling profiling related functions
  to save vm context
     e. acrn_hv_defs.h, list all the profiling command types
