executor: introduce gpa_to_hva() for x86 SYZOS
L1 guest memory is non-contiguous, but previously host setup assumed
the opposite, using L1 guest addresses as offsets in the host memory
block. This led to subtle bugs in IRQ handling (and possibly elsewhere).
Fix this by using gpa_to_hva() to translate guest physical addresses to
host virtual addresses.
This function is cold, so we can afford O(SYZOS_REGION_COUNT) complexity.
