BugLink: https://bugs.launchpad.net/bugs/1949770

Move the declaration of hv_root_partition and hyperv_pcpu_input_arg
from the x86-specific mshyperv.h to the arch independent mshyperv.h
since they are used by arch independent code.  While here, add a
missing #include needed to compile correctly on ARM64.
