CKI KWF Bot 1923ac7a60 Merge: Rebase HyperV to 6.18 for L1VH kernel enablement
MR: https://gitlab.com/redhat/centos-stream/src/kernel/centos-stream-10/-/merge_requests/1849

# Merge Request Required Information

## Summary of Changes

This brings the HyperV subsystem in line with 6.18 and enables the mshv_root driver.

The driver cannot be tested yet, so for now it taints the system and is included in modules-extra. The point of the MR is to ensure the _other_ changes to drivers/hv/ get in before ctc2.

Dropped the following patch due to conflicts:
* tools/hv: fcopy: Fix irregularities with size of ring buffer
* x86/hyperv: Switch to msi_create_parent_irq_domain()

Dropped because the kernel-ark config is [botched](https://gitlab.com/cki-project/kernel-ark/-/merge_requests/4243)
* Drivers: hv: Add CONFIG_HYPERV_VMBUS option
* Drivers: hv: Make CONFIG_HYPERV bool

Already included:
* x86/hyperv: Add kexec/kdump support on Azure CVMs
