This is available in the DopeSheet, GraphEditor, and NLA Editor.
Currently:
- Dopesheet advertises to take selection into account...
-- ...but doesnt - which might be a mistake in rBe3842d1ca4dd
- Graph Editor does not mention selection...
-- ...and also does not take it into account
- NLA does not mention selection...
-- ...but takes it into account
Now:
- make them **all** take selection into account (you can still do a
quick 'Select All' prior to get the full range -- better than not being
able to set this based on selection)
- mention this for all in the tooltip
- also reword to 'Set Preview Range to Selected' since using the term
'Auto' impilies this would change on selection change.

Split some of the code of `graph_edit.c` into:
* `graph_view.c`: preview range, view all, view selected etc.
* `graph_slider_ops.c`: the decimate modal operator code.
The latter file will be extended later with more slider-based operators.
