arm64: entry: Refactor the entry and exit for exceptions from EL1
The generic entry code uses irqentry_state_t to track lockdep and RCU
state across exception entry and return. For historical reasons, arm64
embeds similar fields within its pt_regs structure.
In preparation for moving arm64 over to the generic entry code, pull
these fields out of arm64's pt_regs, and use a separate structure,
matching the style of the generic entry code.
No functional changes.
