KVM: arm64: Spin off helper for programming CPTR traps
A subsequent change to KVM will add preliminary support for merging a
guest hypervisor's CPTR traps with that of KVM. Prepare by spinning off
a new helper for managing CPTR traps.
Avoid reading CPACR_EL1 for the baseline trap config, and start off with
the most restrictive set of traps that is subsequently relaxed.
