renderer_vulkan: Wait on present semaphore at queue submit

The present semaphore is being signalled by the call to acquire the
swapchain image. This semaphore is meant to be waited on when rendering
to the swapchain image. Currently it is waited on when presenting, but
moving its usage to be waited on in the command buffer submission allows
for proper usage of this semaphore.

Fixes the device lost when launching titles on the Intel Linux Mesa driver.
