Log Reflex's frame limit as each of the first 16 swapchains hands it to Streamline again.

Browse Source 
The review found that a play-test item expected nx2_sl.cpp nx2sl_reflex2's line after each resize, fullscreen toggle
or HDR change, but that export logs only its first 8 calls, which the device, the first swapchain, the first
hand-over and a movie use up, so a later rebuild usually logged nothing and the tester would read that as a failure.
vk_dlssg.c vk_dlssg_create_swapchain now logs, for each of the first 16 swapchains with a DLL that has nx2sl_reflex2,
the limit it sent and the one Streamline took ("dlssg: swapchain N: Reflex's mode and frame limit sent again"), on
the present thread under the present and queue locks where reflex_apply already logs a refused limit. The compile
check and -Wall on vk_dlssg.c (no new warnings) pass.
