feat(hcx): add build option to enable FEAT_HCX

FEAT_HCX adds the extended hypervisor configuration register (HCRX_EL2)
and access to this register must be explicitly enabled through the
SCR_EL3.HXEn bit.  This patch adds a new build flag ENABLE_FEAT_HCX to
allow the register to be accessed from EL2.
