Vulkan drivers to solve an issue in the Vulkan SPEC about the
texture-to-texture copies with compressed formats. See #1005
(https://github.com/KhronosGroup/Vulkan-Docs/issues/1005) for more
details.

* vulkan_use_d32s8:
(https://crbug.com/dawn/286):
Vulkan mandates support of either D32_FLOAT_S8 or D24_UNORM_S8. When
available the backend will use D32S8 (toggle to on) but setting the toggle
to off will make it use the D24S8 format when possible.

* vulkan_use_s8:
(https://crbug.com/dawn/666):
Vulkan has a pure stencil8 format but it is not universally available.
When this toggle is on, the backend will use S8 for the stencil8 format,
otherwise it will fallback to D32S8 or D24S8.

* use_placeholder_fragment_in_vertex_only_pipeline:
(https://crbug.com/dawn/136):
Use a placeholder empty fragment shader in vertex only render pipeline.
This toggle must be enabled for OpenGL ES backend, the Vulkan Backend, and
serves as a workaround by default enabled on some Metal devices with Intel
GPU to ensure the depth result is correct.

* use_vulkan_zero_initialize_workgroup_memory_extension:
(https://crbug.com/dawn/1302):
Initialize workgroup memory with OpConstantNull on Vulkan when the Vulkan
extension VK_KHR_zero_initialize_workgroup_memory is supported.

[WebGPU Forced Toggles - enabled]

* disallow_spirv:
(https://crbug.com/1214923):
Disallow usage of SPIR-V completely so that only WGSL is used for shader
modules. This is useful to prevent a Chromium renderer process from
successfully sending SPIR-V code to be compiled in the GPU process.

[Default Supported Features]

* depth_clip_control
* depth32_float_stencil8
* texture_compression_BC
* texture_compression_ETC2
* texture_compression_ASTC
* indirect_first_instance
* RG11B10_ufloat_renderable
* BGRA8_unorm_storage
* dawn_internal_usages
* dawn_multi_planar_formats
* dawn_native
* implicit_device_synchronization
* surface_capabilities
* transient_attachments
