Fix fuchsia build of dawn in chromium

This CL [1] changed the include order in
SemaphoreServiceImplementationZirconHandle.cpp and uncovered an existing
IWYU issue for VkPhysicalDevice, causing the build failure in [2],
preventing dawn->chromium rolls. I have verified all of this locally.
Fix by including the appropriate header for VkPhysicalDevice.
