Drivers: hv: Make CONFIG_HYPERV bool

With CONFIG_HYPERV and CONFIG_HYPERV_VMBUS separated, change CONFIG_HYPERV
to bool from tristate. CONFIG_HYPERV now becomes the core Hyper-V
hypervisor support, such as hypercalls, clocks/timers, Confidential
Computing setup, PCI passthru, etc. that doesn't involve VMBus or VMBus
devices.
