Yifan Liu 702a71639f hv: Add two vlapic APIs ...

Sometimes HV would like to know if there are specific interrupt
pending in vIRR, and clears them if necessary (such as in x86_tee case).

This patch adds two APIs: get_next_pending_intr and clear_pending_intr.
This patch also moves the inline api prio() from
vlapic.c to vlapic.h

v3:
    Remove apicv_get_next_pending_intr and apicv_clear_pending_intr
    and use vlapic_get_next_pending_intr and vlapic_clear_pending_intr
    directly.

v2:
    get_pending_intr -> get_next_pending_intr
    apicv_basic/advanced_clear_pending_intr -> apicv_clear_pending_intr
    apicv_basic/advanced_get_pending_intr -> apicv_get_next_pending_intr
    has_pending_intr kept
