For some unknown reason, during the Chromium build, the
third_party/dawn/third_party:glfw always get rebuilt even when
nothing actually references is (as is the case for "is_fuchsia ==
true").
This ends up in a build failure, since glfw doesn't support this
platform. See [1] for an example.
This CL is a work-around that makes the library empty for Fuchsia
instead. Note that this is never linked into anything so should
not be an issue for any Chromium-related code either.

The Fuchsia platforms relies on a number of Vulkan extensions
that have not been upstreamed to Khronos yet, and thus are not
part of the official Vulkan headers (i.e. <vulkan/vulkan.h>).
This CL adds a new header under src/common/ that contains these
declarations, extracted from the Fuchsia source tree, and ensures
they are included automatically from <common/vulkan_platform.h>
This is necessary to support certain features when building
Dawn on Fuchsia.
IMPORTANT NOTE: Some of the things declared in this header will
change once everything is upstreamed, which will require updating
the source code using them. For example,
VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_TEMP_ZIRCON_EVENT_BIT_FUCHSIA
Will likely be renamed officially as:
VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_ZIRCON_EVENT_BIT
And will be assigned a new value by Khronos.

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.
