aarch64: Add public syscall ABI
We use largely the same ABI as Linux: a syscall is invoked with the
"svc #0" instruction, passing arguments the same way as for a regular
function call. Specifically, up to 8 arguments are passed in the x0-x7
registers, and the rest are placed on the stack (this is only necessary
for the vm_map() syscall). w8 should contain the (negative) Mach trap
number. A syscall preserves all registers except for x0, which upon
returning contains the return value.
