Sebastian Franco 1e4e50149b Reorder code so we can use different displays on the preview render
The existing code almost have the avility to use different display
for the preview by providing a different display id, this change
just make sure the InvariantDeviceProfile is created after we
create a new context with the desired display and we need to use
the default display for the SurfaceControlViewHost

Test: Manual testing, changing the display id on FixedWidthDisplayRatioFrameLayout
Bug: 292152331
Change-Id: I450d94a9a3f1a6a7b0c2b0722a11cf335122de05
