arm64: Add ESR fault helpers
Add helper functions which operate directly on an ESR value rather than
trying to access the register itself.
These mirror equivalent KVM vCPU wrappers in kvm_emulate.h and allow those
wrappers and KVM's stage-2 fault handling to operate on a plain ESR value.
This is needed to later generate a synthetic fault for the stage-2 page
table pre-faulting mechanism.
No functional change intended.
