traps: x86: converge trap_init functions
- set_system_gate on i386 is really set_system_trap_gate
- set_system_gate on x86_64 is really set_system_intr_gate
- ist=0 means no special stack switch is done:
- introduce STACKFAULT_STACK, DOUBLEFAULT_STACK, NMI_STACK,
DEBUG_STACK and MCE_STACK as on x86_64.
- use the _ist variants with XXX_STACK set to zero
- remove set_system_gate
