Improve the CPUID emulation of basic leaves:
 - Hide DCA and PQM, they cannot be used in guests.
 - On Intel, explicitly handle each basic leaf until 0x16.
 - On AMD, explicitly handle each basic leaf until 0x0D.

Respect the convention for the hypervisor information: return the highest
hypervisor leaf in 0x40000000.EAX.

Improve the CPUID emulation on nvmm-intel: limit the highest basic and
hypervisor leaves.

Complete rev1.26: reset nvmm_impl to NULL in nvmm_fini().
