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
