x86/cpu: Detect FreeBSD Bhyve hypervisor
Detect the Bhyve hypervisor and enable 15-bit MSI support if available.
Detecting Bhyve used to be a purely cosmetic issue of the kernel printing
'Hypervisor detected: Bhyve' at boot time.
But FreeBSD 15.0 will support¹ the 15-bit MSI enlightenment to support
more than 255 vCPUs (http://david.woodhou.se/ExtDestId.pdf) which means
there's now actually some functional reason to do so.
