Add a new capability, VM_CAP_ENABLE_INVPCID, that can be enabled to expose
'invpcid' instruction to the guest. Currently bhyve will try to enable this
capability unconditionally if it is available.
Consolidate code in bhyve to set the capabilities so it is no longer
duplicated in BSP and AP bringup.
Add a sysctl 'vm.pmap.invpcid_works' to display whether the 'invpcid'
instruction is available.
