Found while investigating Swiftshader support. Some Vulkan loaders
fail to create an instance if VK_ICD_FILENAMES is empty string
rather than entirely absent. It was set to empty string because
Dawn did not distinguish between nonexistent environment variables
and the empty string. This CL adds distinguishing between the two,
including tests for the behavior.

This will help check that the Vulkan devices are enough for WebGPU in
a following CL.
In addition to additional limits this CL:
- Change maxColorAttachments 4 -> 8 to match WebGPU
- Renames kMinDynamicBufferOffsetAlignment to
kMinUniformBufferOffsetAlignment.
- Renames kMaxVertexBufferStride to kMaxVertexBufferArrayStride.
- Changes validation of buffer offsets to use the separate uniform and
storage limits (but no test is added because they are the same).
- Adds validation and a test for kMaxStorageBufferBindingSize.
- Augment the null::Device memory limit for that new test (it allocates
a buffer of 512MB).
- Fix the maxColorAttachment test to not use hardcoded values.

Deprecates the computeStage member of the descriptor in favor of compute
as described by the spec. In order to support both variants without
breaking backwards compatibility some code had to be manually added to
the wire client to copy from the deprecated member to the new one and
visa versa.

This permits enabling the OpenGL and OpenGL ES backends independently.
This change also enables the OpenGL ES backend on Windows.
This will cause the end2end tests to run on OpenGL ES on the
GPU-less bots, via SwANGLE.

Still leave deprecated `depth` functional as there are some references in

invalid. Add DeprecatedAPITests.

The WGSL spec has been updated with 'Default Struct Layouts':
https://github.com/gpuweb/gpuweb/pull/1447
This removes the `[[offset(n)]]` decoration, and replaces it with two optional decorations: `[[size(n)]]` and `[[align(n)]]`, and a sensible set of sizes and alignments for each type.
Most `[[stride(n)]]` decorations have also been removed from arrays.

Fix a bug about mipmap level in SamplerFilterAnisotropicTests.
Sizes of the 3 miplevels should be 4,2,1.
The old code allocates 8,4,2 (which don't have a 1x1 level)
Expected rendered pixel values have to change.
The render result now fits the webgl demo at https://jsfiddle.net/t8k7c95o/5/

This is enough to get all of the sample apps running on a conformant ES 3.1 implementation, such as ANGLE/Vk or NVidia's OpenGL ES Linux driver.
Implements a new opengl::AdapterDiscoveryOptionsES subclass to specify its creation at adapter discovery time.
Adds a "-b opengles" command-line flag to the code samples.
Asserts on a call to glShaderStorageBlockBinding() on ES.
Works around missing indexed draw buffers support by asserting when a non-0 color attachment is specified.
Works around missing glClearTexSubImage() by asserting. :/
These will likely require front-end validation.

This makes a nearly one-to-one mapping between the JS and C APIs, which
benefits projects like Blink and Emscripten.
- JavaScript's `undefined` is equivalent to C `WGPU_STRIDE_UNDEFINED`.
- JavaScript's `0` is equivalent to C `0`.
- To implement the API correctly, Blink must special-case an actual
value coming in from JS that is equal to WGPU_STRIDE_UNDEFINED
(0xFFFF'FFFF), and inject an error.
Keeps but deprecates a reasonable approximation of the old behavior.
