KVM: arm64: Use ESR helpers in guest abort handling

Convert kvm_vcpu_* ESR wrappers in kvm_emulate.h and the stage-2 abort
handling logic in mmu.c to use the newly introduced ESR helpers.

kvm_is_write_fault() is split in two, with esr_abt_is_write_fault()
handling the esr parts of the operation and kvm_is_write_fault() wrapping
it.

Introduce/modify kvm_s2_fault_is_{perm,exec,write}(),
kvm_s2_perm_fault_granule() so the abort path reads the ESR from a single
place.

This is to allow a later change to permit stage 2 pre-faulting via a
synthetic ESR value.

Remove now-unused kvm_vcpu_dabt_is_cm(), kvm_vcpu_trap_is_exec_fault() and
kvm_vcpu_trap_get_perm_fault_granule().

No functional change intended.
