This adds swiftshader as a dependency of Dawn, and when it is present
dawn_use_swiftshader=true will force usage of it. (due to a Vulkan
loader limitation we can't have both regular drivers and swiftshader in
the same VkInstance).

This reverts commit 1954436fe2.
Reason for revert:
The shaderc side of this multi-patch brings in a dependency on glslang, which uses a static initializer, which chromium doesn't like.

An earlier CL [1] enabled Vulkan validation layers on Linux which
also enables validation layers on Chrome OS. Unfortunately, this
changes breaks the Chrome OS build of Dawn:
.../vulkan.h:63:10: fatal error: 'xcb/xcb.h' file not found
This is because including the validation layers also includes
the Vulkan-Headers repo which has a BUILD file that defines
VK_USE_PLATFORM_XCB_KHR [2]. XCB (and all of X11, for that matter)
is not supported on Chrome OS even though it is a Linux platform.
This is a quick fix for the problem to unbreak the BUILD, but I
think we should discuss what a long-term fix looks like. Do we send
a patch to Khronos to add an "is_chromeos" branch to their BUILD
file a la Fuchsia?
Also, as mentioned by cwallez@ in a different CL of mine, we should
really set up a Chrome OS trybot to catch these earlier. I can
assign a bug to myself for that!

When vkDestroyDebugReportCallbackEXT() is called in Backend::~Backend()
and Vulkan validation layers are in use, the variable unique_id_mapping
is referenced internally[1]. However, the variable is global[2] and it's
destructed before Backend::~Backend(), which causes a use-after-free
issue. The issue was unnoticed on Windows, but we observed the crash at
exit on Linux.

This adds a flag to enable using the reflection compiler from
SPIRV-Cross, and also updates the build rules to make sure that the
GLSL compiler is also present when using reflection, since the

Enable the Vulkan backend when building Dawn with
the Chromium build system for Fuchsia. To make this
work properly the following is required:
- Modify VulkanInfo.cpp and BackendVk.cpp to correctly probe
the Fuchsia swapchain layer and its layer extension, as well
as enabling them when creating a new VkInstance.
- Modify VulkanFunctions.cpp to load the Fuchsia swapchain
related extension for this platform only.
- Provide a small mock GLFW library for Fuchsia under
src/utils/Glfw3Fuchsia.cpp, since the upstream project
does not support this platform at all. Its purpose is
only to allow the creation of the right VulkanBinding
instance, which depends on the creation of a display
surface for latter swapchain creation.
- Add //third_party/fuchsia-sdk:vulkan_base and
//third_party/fuchsia-sdk:vulkan_validation as
data_deps of the libdawn_native_sources target in
order to ensure that the Fuchsia package created by
the build system will include the correct Vulkan
libraries (loader and validation layers).
This builds correctly, and both dawn_unittests and
dawn_end2end_tests will run on a real Fuchsia device
or inside the Fuchsia emulator, using either GPU
virtualization or a software-based renderer.
Note: dawn_unittests will also run inside QEMU, but
not dawn_end2end_tests, since the latter requires
proper GPU emulation which is not available in this
environment.
NOTE: All end2end tests pass using a device with
an "Intel HD Graphics 615 (Kaby Lake GT2)"
adapter. However:
- For some reason, a single test takes up
to 129 seconds to pass
(BufferSetSubDataTests.ManySetSubData/Vulkan).
- The test process crashes inside VkDestroyInstance(),
apparently inside the Fuchsia-specific imagepipe
layer (which implements swapchain support).
This is likely a bug in the layer itself, and
not Dawn.
Also, may end2end tests will crash when run inside
the Fuchsia emulator (which uses GPU virtualization
to talk to the host GPU). The crashes happen inside
libvulkan-goldfish.so, the emulator-specific Vulkan
ICD on this sytem. Not a Dawn bug either.

- Removes the X11 dependency for Chrome OS builds because we do not

- Removes the XCB dependency (again, no X11).
