In a typical application, most draws will use different uniforms values for
things like the world position and orientation. In the current state of WebGPU
this means that a new bind group needs to be created for each draw to set the
right uniforms. Bind group creation is expected to be more expensive than
recording draws because they incur an allocation.
This feature is to reduce the number of bind groups that need to be
created.
The patch implemented dynamic buffer offset validation logics and adding unittests.

Error objects that are cached still have mIsBlueprint to false and would
try to uncache themselves, which isn't valid.
Also adds a regression test.

Dawn used to return "nullptr" when an error happened while creating an
object. To match WebGPU we want to return valid pointers but to "error"
objects.
This commit implements WebGPU error handling for all "descriptorized"
objects and changes the nullptr error checks into "ValidateObject"
checks. This method is used both to check that the object isn't an
error, but also that all objects in a function call are from the same
device.
New validation is added to objects with methods (apart from Device) so
they check they aren't error objects.
A large number of ASSERTs were added to check that frontend objects
aren't accessed when they are errors, so that missing validation would
hit the asserts instead of crashing randomly.
The bind group validation tests were modified to test the behavior with
both nullptrs and error objects.
Future commits will change the CommandBufferBuilder to not be a builder
anymore but an "Encoder" instead with special-cased error handling. Then
once all objects are descriptorized, the notion of builders will be
removed from the code.

Undefined BGLs are stored as nullptr in the pipeline layout, so to be
defensive we assert clients of PipelineLayout can't request undefined
BGLs (which forces iteration on the BGLMask).
Also fix two cases where the BGLs were iterated on incorrectly.

New additions to the validation for the WebGPU execution environment
broke all the tests that use shaders because tests don't produce valid
SPIR-V for WebGPU and also backends don't know how to lower
WebGPU-flavored SPIR-V to target languages.
Also rolls SPIRV-Headers to a version compatible with SPIRV-Tools

The error type will help distinguish between validation errors, context
losts and others which should be handled differently.
Take advantage of advantage of this to change DAWN_RETURN_ERROR to
"return DAWN_FOO_ERROR" to have the return be more explicit. Also
removes usage of DAWN_TRY_ASSERT for more explicit checks.

This integrates spirv-val in dawn_native so that regular and
WebGPU-specific validation of shaders is done.
Also adds tests to check OpUndef is correctly rejected so we know
WebGPU-specific validation is working.
