Missing vkCmdWaitEvents checks

[spencer-lunarg]

Seem like some simple (hopefully) checks

• VUID-vkCmdWaitEvents-pEvents-03847
• VUID-vkCmdWaitEvents2-pEvents-03839
• VUID-vkCmdWaitEvents2-pEvents-03840
• VUID-vkCmdWaitEvents2-pEvents-03841

This can be part of bigger event work mentioned in some other recent issues (the inactive part that lives in syncval and also part of the event tracking that does not working properly for some cross command buffer or secondary cases).
