Implement handling for the AArch64 SP_EL0 system register. This holds the EL0 stack pointer, and is only accessible when it's not being used as the stack pointer, ie when we're in EL1 and EL1 is using its own stack pointer. We also provide a definition of the SP_EL1 register; this isn't guest visible as a system register for an implementation like QEMU which doesn't provide EL2 or EL3; however it is useful for ensuring the underlying state is migrated. We need to update the state fields in the CPU state whenever we switch stack pointers; this happens when we take an exception and also when SPSEL is used to change the bit in PSTATE which indicates which stack pointer EL1 should use.
