zink: clamp swapchain renderarea instead of asserting

Browse source 
in a sequence like:
* resize A
* clear
* resize B
* clear
* resize C
* clear

for a swapchain resource, the geometry for a given op after the resize
may desync for the op with which it was executed, but this is fine
since the underlying swapchain object will have to be re-created anyway

fixes #10827
