[PATCH 1/4] xen/link: Introduce a common BUGFRAMES definition



Bugframe linkage is identical in all architectures.  This is not surprising
given that it is (now) only consumed by common/virtual_region.c

Introduce a common BUGFRAMES define in xen.lds.h ahead of rearranging their
structure.

No functional change.
