Fix DialogClientView layout, buttons, accelerators; etc.

Rename Get[Extra|Footnote]View to Create*; only call once per dialog.
Clamp 'extra view' size and align left in the button row.
Simplify 'extra view' users: remove containers/layout, init on demand.

Remove unused GetSizeExtraViewHeightToButtons / IsDialogButtonVisible / GetFootnoteViewHeight.

Remove non-functional PaintSizeBox code and broken |size_box_bounds_|.
Move meaningful StyleParams distinctions to GetInsets().
(temporarily regresses new dialog style resizing and button spacing)

Get default button text in DialogDelegateView::GetDialogButtonLabel.
Return superclass GetDialogButtonLabel in OVERRIDES, not string16().

Simplify FocusChangeListener add/remove for default button wrangling.
Add TreeView return key accelerator handling to commit pending edits.
Remove AreAcceleratorsEnabled (was for committing tree view, edits)

Fix [Dialog|Widget]Example's init; add extra/footnote views.

TODO(followup): Restore dialog resizing via frame view hit testing.
TODO(followup): Fix new dialog button spacing via layout constants.

BUG=166075
TEST=No observable dialog appearance/behavior changes (except minor button spacing change for experimental --enable-new-dialog-style)
