Add an API to rendezvous all active vcpus in a virtual machine. The rendezvous
can be initiated in the context of a vcpu thread or from the bhyve(8) control
process.

The first use of this functionality is to update the vlapic trigger-mode
register when the IOAPIC pin configuration is changed.

Prior to this change we would update the TMR in the virtual-APIC page at
the time of interrupt delivery. But this doesn't work with Posted Interrupts
because there is no way to program the EOI_exit_bitmap[] in the VMCS of
the target at the time of interrupt delivery.
