Reland "[Linux/Ozone/Wayland] Support fractional-scale-v1"

This is a reland of commit 5e6a7691b5f63df3e30173f073ae8e9f697d5228

Changes from original CL:
 - Actually use wp_viewporter to rescale the window to the correct
   logical size
 - Automatically disable overlay delegation when fractional_scale_v1 is
   enabled
 - Use viewporter to ensure that the drag image has the correct size
 - Adjust CreateAndAddRegion (and users) to properly scale input and
   opaque regions for fractional scaled surfaces.
 - Crop surfaces as appropriate to ensure display pixel precision
