hv: Variable/macro renaming for intr handling of PT devices using IO-APIC/PIC

Browse Source 
1. Renames DEFINE_IOAPIC_SID with DEFINE_INTX_SID as the virtual source can
   be IOAPIC or PIC
2. Rename the src member of source_id.intx_id to ctlr to indicate interrupt
   controller
2. Changes the type of src member of source_id.intx_id from uint32_t to
   enum with INTX_CTLR_IOAPIC and INTX_CTLR_PIC
