The current grouping preserves the order: xrefs are grouped by the
string returned by xref-location-group and both the order of the groups
and the order of xrefs within the group is preserved. See
xref--alistify.

Theoretically this can already be done by ignoring xref-location-group
or by specializing xref-location-group for xref-etags-location so that it
returns always the same group.

Thinking about it: for etags it would make sense to group xrefs by name
of the TAGS file because etags--xref-find-definitions doesn't sort xrefs
"globally"; xrefs are reordered only within a TAGS file.
