target/arm: Implement gdbstub pauth extension
The extension is primarily defined by the Linux kernel NT_ARM_PAC_MASK
ptrace register set.
The original gdb feature consists of two masks, data and code, which are
used to mask out the authentication code within a pointer. Following
discussion with Luis Machado, add two more masks in order to support
pointers within the high half of the address space (i.e. TTBR1 vs TTBR0).
