Bug 1447056 part 1 - Move eWindowType_sheet to be before eWindowType_popup. r=mstange

nsBaseWidget::BoundsUseDesktopPixels() states that window types before
eWindowType_sheet take desktop pixels rather than device pixels for
parameters of Move and Resize.

Cocoa widget seems to treat all of them as desktop pixels, and sheet is
one of the window types that it can actually open, so it should be put
before popup so that BoundsUseDesktopPixels() is correct on that.
