[3/n] Add VulkanQueueSubmitWithCommands feature to guest

Bug: 177241396

+ Also make sure rcEncoder() is active for each Vulkan thread. It looks
like we don't always ensure that, which allows leaking of render threads
on host after guest process shutdown, since the host needs the process
id info for each guest thread.
