Oliver Upton fb10ddf35c KVM: arm64: Compute per-vCPU FGTs at vcpu_load() ...

To date KVM has used the fine-grained traps for the sake of UNDEF
enforcement (so-called FGUs), meaning the constituent parts could be
computed on a per-VM basis and folded into the effective value when
programmed.

Prepare for traps changing based on the vCPU context by computing the
whole mess of them at vcpu_load(). Aggressively inline all the helpers
to preserve the build-time checks that were there before.
