KVM: nVMX: Move EVMCS1_SUPPORT_* macros to hyperv.c

Move the macros that define the set of VMCS controls that are supported
by eVMCS1 from hyperv.h to hyperv.c, i.e. make them "private".   The
macros should never be consumed directly by KVM at-large since the "final"
set of supported controls depends on guest CPUID.

No functional change intended.
