Reland "Search for system libvulkan on CrOS" Currently, ANGLE searches in the "module" directory for libvulkan during init on CrOS. The library doesn't exist at this location (/opt/google/chrome/libvulkan.so), and we should instead just call dlopen(libvulkan.so) to search the system library paths. The original CL was reverted because it broke MSAN builds of ChromeOS-on-Linux (CrOS UI that runs on a generic Linux machine). The original CL caused these builds to use the Linux system Vulkan loader library which is most likely not built with MSAN. This caused MSAN violations when combined with an ANGLE built with MSAN [1]. The reland fixes this issue by only using the system libvulkan on real ChromeOS devices.
