UI: Keep edit mode and the base when changing the patch range

Changing the patch range while in edit mode silently dropped the edit
mode, because <gr-file-list-header> did not pass `edit` on to
`createChangeUrl()`. And even with `edit` preserved the resulting URL
was not routable: the CHANGE_EDIT pattern accepted a single positive
patchset only, so neither a patch range nor a merge parent could be
expressed. Editing a merge commit with a parent as the base was
therefore impossible.

Let CHANGE_EDIT accept the same range expression as CHANGE, read the
base in `handleChangeEditRoute()`, and keep the base when entering and
leaving edit mode. Entering edit mode uses the view model value, so that
a URL without a base stays without one.

Edit mode is only kept when the patchset itself stays the same, i.e. when
just the base changes. A change edit is based on one specific patchset:
modifications always go into the existing edit, no matter which patchset
is being displayed, and only an edit based on the current patchset can be
published. So following along to another patchset would only pretend that
the edit does.

Release-Notes: Fixed losing edit mode when changing the diff base.
