radv: copy the number of viewports/scissors at pipeline bind time 

The number of viewports/scissors can only be specified at pipeline
creation time, so make sure to copy them when binding a new one
because the dynamic state is cleared in BeginCommandBuffer().

Fixes: dcf46e995d ("radv: do not update the number of scissors in vkCmdSetScissor()")
Fixes: 60878dd00c ("radv: do not update the number of viewports in vkCmdSetViewport()")
