Create VulkanImageWrappingTests for dma-buf images

This CL branches the existing VulkanImageWrappingTests to separate
tests for OpaqueFD-backed amd DmaBuf-backed external images. On
Chrome OS of Dawn, we no longer interop using opaque FDs, so these
tests were failing in the end2end test suite.

The new VulkanImageWrappingTestsDmaBuf tests are essentially 1:1
mappings of their counterparts in the Opaque FD version. The only
difference is that we allocate memory directly on the device using
GBM instead of creating a VkImage (which will likely call some GBM
methods under the hood) and then extracting the FD using a Vulkan
extension. We then communicate this to Dawn via the DmaBuf
ExternalImageDescriptor.

Also, this fixes VulkanImageWrappingUsageTests::LargeImage on AMD
devices (assuming the extension is implemented) as we can now
specify DRM modifiers.
