arm64: ipipe: route traps to co-kernel
This commit introduces the changes redirecting traps and exceptions to the interrupt pipeline, so that the co-kernel can be made aware early on. The co-kernel may then decide whether the fault should be propagated to the regular kernel for actual handling. This is typically useful for allowing the co-kernel to downgrade the current context from the head domain to the root domain, when leaving the burden of handling major faults to the regular kernel makes more sense than expecting the co-kernel to reinvent such a wheel (e.g. memory violations, illegal instructions, divide by zero etc). As a matter of fact, optimizing latency upon such events would not make much sense anyway.
