xen/intr: improve PIRQ handling
Improve and cleanup the Xen PIRQ event channel code:
- Remove the xi_shared field as it is unused.
- Clean the "pending" bit in the EOI handler, this is more similar to how
native interrupts are handled.
- Don't mask edge triggered PIRQs, edge trigger interrupts cannot be
masked.
- Panic if PHYSDEVOP_eoi fails.
- Remove the usage of the PHYSDEVOP_alloc_irq_vector hypercall because
it's just a no-op in the Xen versions that are supported by FreeBSD Dom0.
