593fe98d74 igvm: add support for initial register state load in native mode
Add IgvmNativeVpContextX64 struct holding the register state (see igvm
spec), and the qigvm_x86_load_context() function to load the register
state.

Wire up using two new functions: qigvm_x86_set_vp_context() is called
from igvm file handling code and stores the boot processor context.
qigvm_x86_bsp_reset() is called from i386 target cpu reset code and
loads the context into the cpu registers.

13abf2fcb7 igvm: add support for igvm memory map parameter in native mode
Add and wire up qigvm_x86_get_mem_map_entry function which converts the
e820 table into an igvm memory map parameter.  This makes igvm files for
the native (non-confidential) platform with memory map parameter work.
