Vulkan: Support submitting multiple semaphores With GL_EXT_semaphore, the client can create and submit semaphores to synchronize with an external vulkan instance. We need to be able to submit semaphores from both the current surface as well as the client. In order to support glWaitSemaphoreEXT, make ContextVk hold a vector of semaphores that will be submitted with the next batch. In order to support glSignalSemaphoreEXT, make ContextVk::flush() build a vector of semaphores to submit, rather than just one. Submissions that result from a client signal operation will need to signal both the client semaphore as well as a semaphore from the surface's semaphore chain.
