ui/views: Remove redundant Save/Restore in LocationBarView.

ui/views: Remove redundant Save/Restore in LocationBarView.

LocationBarView::PaintChildren does a Save/Restore around calling Paint
on another View. But View::Paint() is non-virtual and already does a
save/restore around any work that it does (eg around OnPaint()). So
this is redundant work.

This ScopedCanvas was introduced by
https://codereview.chromium.org/302453002/diff/120001/chrome/browser/ui/views...
which also added some clipping and moved the omnibox_view_ painting out of the
normal child painting loop.

Since then, the clips were removed but the ScopedCanvas remained. And the other
things pulled out of the paint children loop were also removed. There's no
reason left to paint the omnibox_view_ specially, so we can just call
View::PaintChildren.
