Adds generated headers in dawn_native for object type tracking similar to that used in dawn_wire. Splits ObjectBase into ObjectBase and ApiObjectBase for clearly differentiation, and adds virtual function to identify the type of ApiObjects. Updates error generation to utilize new object typing for generating messages.

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.

This change is a preparation for making the compute pass track the
synchronization scope usages per dispatch instead of for the whole pass.
This CL just separates the Compute and RenderPassResourceUsage types.
This requires making the difference between
SyncScope/ComputePass/RenderPass ResourceUsageTracker instead of having
a single combined tracker.
This change also duplicates SetBindGroup by removing the common handling
in ProgrammablePassEncoder and putting it in ComputePassEncoder and
RenderEncoderBase. This is necessary because the UsageTracker types are
now split, but it will also help have different handling of SetBindGroup
for compute and render in follow-up CLs.
There are no functional changes.

of different types from being used interchangably in Debug builds.
It also adds ityp::{array,bitset,span} as helper classes to wrap std::
versions (not span). These accept a template paramter as the Index type
so that typed integers, or enum classes, may be used as a type-safe
index.
For now, bind group layout binding indices use TypedInteger. Future

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

recording draws because they incur an allocation.

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.
