The variable use_x11 in Chromium takes into account more thinks like
whether we are building in LaCrOS mode and more. If we don't do this,
compilation of Chromium fails when Dawn tries to include X11/Xlib.h

Corentin Wallez 0925720ecb Add the Vulkan loader as an optional dependency and use it on Mac
On macOS we can't rely on having the Vulkan loader installed in the
system. So we add the Vulkan loader as an optional dependency of Dawn
and use it on macOS when building Dawn in standalone with Vulkan
support.

Usage of building our own loader might broaden if the loader gains
features that are useful on other OSes. For example the ability to pass
in the "root ICD" entrypoint to the loader so we can have both
Swiftshader and the system driver at the same time.

Corentin Wallez b31015b836 Split examples, test and utils in their own BUILD.gn
The basic change was to copy-paste targets in the new BUILD.gn files and
fixup paths / add includes. There's a couple more changes that had to be
done at the same time:

 - Multiple files need to know if GLFW is supported so the variable was
moved to dawn_features.gni.
 - The gtest_and_gmock target used to abstract between Dawn's copy of
GTest/GMock is only needed by tests and was moved in src/tests/BUILD.gn.
 - A leftover dawn_end2end_tests target is left in the main BUILD.gn
file that is an exact copy of the on in src/tests/BUILD.gn. This is
because the GN path is hardcoded in Chromium's isolate_map.pyl that also
can't support GN groups. The only way to move a target I could figure
out was to duplicate it temporarily.

Austin Eng eb1ca45df7 Fix Vulkan fuzzer on mac_libfuzzer_chrome_asan
This commit fixes two problems:
1) It includes testing/libfuzzer/libfuzzer_exports.h which exports
   the LLVMFuzzerInitialize symbol. On Mac, not doing so causes it
   to be removed by the linker.
2) It makes it so that dawn_use_swiftshader is enabled by default
   when fuzzing, and enabling swiftshader also enables the Vulkan
   backend.

Corentin Wallez 3a1746e71c Introduce wgpu::Surface and implement it for HWND, X11 and Metal
This is another step to implement webgpu.h swapchains, Surface is
essentially a union type of all the types of windows that can be used to
create swapchains.

Changes to allow implementing wgpu::Surface and test its creation are:

 - Add GLFWUtils.cpp/.h/_metal.mm  that contains helpers used to use
WebGPU with GLFW. This deprecates BackendBinding.h that will be removed
when the NXT swapchain is removed.
 - Add a `dawn_use_x11` GN variable to factor all the places in BUILD.gn
where we checked whether we should use X11.
 - Add a `supports_glfw_for_windowing` GN variable in the main BUILD.gn
file to control which configuration tests and samples using GLFW can be
built.
 - Add a ObjCUtils.h to contain some ObjC functionality that we'd need
in files that otherwise would be C++ (so that they can be compiled on
all platforms).

Austin Eng c3609d224a Reland "Use Swiftshader by default when fuzzing"
This is a reland of d08a14b709

It gates dawn_use_swiftshader on dawn_enable_vulkan because the
Vulkan backend isn't supported on Mac. We may support Swiftshader
Vulkan on Mac in the future, but that will first require changes
to how we initialize the Vulkan backend.

Brian Ho 858f93b86f Disable Vulkan validation layers on Chrome OS
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!

Li, Hao 0e1bef3251 Add Vulkan validation layers on Windows
Deploy self-built Vulkan validation layers instead of system installed
one. And it will reuse third_party/angle's Vulkan validation layers if
building with chromium.

Ryan Harrison d561448d0d Add build time flag to control enabling SPIRV-Cross reflection
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
reflection compiler subclassess the GLSL compiler.

David 'Digit' Turner b749d07ac9 Enable Vulkan for Chromium Fuchsia build.
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.

Brian Ho 0ebd54cf38 Update BUILD flags to support Chrome OS
This CL updates a few flags to support Chrome OS:

- Disables the OpenGL backend on Chrome OS builds.
- Removes the X11 dependency for Chrome OS builds because we do not
support X11.
- Removes the XCB dependency (again, no X11).

Corentin Wallez 03f64292ad dawn_features.gni: add an option to complete static libraries
This is useful for people using Dawn's standalone build to compile
static libraries to use in other projects. Without this static libraries
will act as source sets as is GN's default.
