DsExpr: Rip out static/dynamic check in list desugaring
Previously we would try to break explicit lists into a dynamic prefix
and static tail and desugar the former into a `build` expression.
Unfortunately, this heuristic resulted in surprising behavior
(see #11710) and wasn't pulling its weight. Here we drop it (along with
the `-fsimple-list-literals` flag), leaving only the list length
heuristic to determine whether `build` or cons list desugaring should be
used.
