Sliders: Add function that changes widgets position on layout

Browse Source 
Changes the layout to QGridLayout and adds function to change widgets
position on the layout depending on the windows aspect ratio. Before
this the widgets wouldn't fit on screen when using the example on
Android in portrait.

Fixes: QTCREATORBUG-27685
Pick-to: 6.2 6.3 6.4
