Previously the .debug_line.dwo section was only emitted only if type
units are present. This patch further extends emission for the case if
.debug_macro.dwo section is present.

For enabling this, I've refactored out `SplitLineTable` from
`DwarfTypeUnit` to `DwarfUnit` so that it can be emitted for when
type units are not present. Emission is further restricted to only
when `.debug_macro.dwo` section is present.

Ideally, this should've splitted into more than one patches, but
that can be done post review. This patch is intended to convey the overall
direction.
