uml: create as-layout.h

This patch moves all the the symbols defined in um_arch.c, which are mostly
boundaries between different parts of the UML kernel address space, to a new
header, as-layout.h.  There are also a few things here which aren't really
related to address space layout, but which don't really have a better place to
go.
