Reto Buerki c7cadf52a6 hw_x86_64: setup ISR and IDT
* Add isr.s assembler file:
    The file declares an array of Interrupt Service Routines (ISR) to handle
    the exception vectors from 0 to 19, see Intel SDM Vol. 3A, section
    6.3.1.
* Add Idt class:
  * The class Genode::Idt represents an Interrupt Descriptor Table as
    specified by Intel SDM Vol. 3A, section 6.10.
  * The setup function initializes the IDT with 20 entries using the ISR
    array defined in the isr.s assembly file.
* Setup and load IDT in Genode::Cpu ctor:
    The Idt::setup function is only executed once on the BSP.
* Declare ISRs for interrupts 20-255
* Set IDT size to 256
