HV: Add hypercall to set/clear IRQ line

Browse Source 
- wraps ASSERT/DEASSERT IRQ line hypercalls.
    - remove 'intr_type' from set/clear IRQ line interface.
    - deprecate "IRQ_ASSERT", "IRQ_DEASSERT" & "IRQ_PULSE".
    - new adding hypercall will support "GSI_SET_HIGH"/
      "GSI_SET_LOW"/ "GSI_RAISING_PULSE"/ "GSI_FALLING_PULSE"
      operations
