Use updated window size in bevymark example (#3335)

Browse source 
# Objective

Have the bird spawning/collision systems in bevymark use the proper window size, instead of the size set in WindowDescriptor which isn't updated when the window is resized.

## Solution

Use the Windows resource to grab the width/height from the primary window. This is consistent with the other examples.
