KVM/arm64 fixes for 6.14, take #2

- Large set of fixes for vector handling, specially in the interactions
  between host and guest state. This fixes a number of bugs affecting
  actual deployments, and greatly simplifies the FP/SIMD/SVE handling.
  Thanks to Mark Rutland for dealing with this thankless task.

- Fix an ugly race between vcpu and vgic creation/init, resulting in
  unexpected behaviours.

- Fix use of kernel VAs at EL2 when emulating timers with nVHE.

- Small set of pKVM improvements and cleanups.
