Various Wayland DPI scaling fixes

Browse Source 
Use the glfw window content scale api to get the DPI for windows.
Likely, more accurate than our logic to find the overlapping monitor
to get the DPI.

Also, after a DPI change event send a fake resize event to workaround
render surface not being properly updated.

Fixes #1143
