Assert on valid order of which ids in ranges on SfxItemSet creation

This allows to make sure we actually use sorted which ranges,
and then it's safe to call SfxItemSet::MergeRange when needed.

Also this change relaxes the previous requirement that ranges
must be separated by at least one; this allows to have adjacent
ranges, like in

RES_FRMATR_BEGIN, RES_FRMATR_END-1,
RES_GRFATR_BEGIN, RES_GRFATR_END-1,

where RES_FRMATR_END is equal to RES_GRFATR_BEGIN. Allowing this
makes possible to (1) self-document the ranges, so it's clear
which ranges are included; and (2) be safe in case when these
constants would change, so that the one merged range would not
unexpectedly contain everything inserted between RES_FRMATR_END
and RES_GRFATR_BEGIN.
