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.

ObjectBase will contain data that all WebGPU objects have such as a
pointer back to the device, a refcount (via inheriting from RefCounted),
a name, an error status etc.

The dawn.h and dawncpp.h structure definitions references dawnFoo or
dawn::Foo respectively when it should reference dawn_native::FooBase* in
dawn_native. Autogenerate files to declare the dawn_native version of
the structs and change the ProcTable generation to use it instead.
This is important to make libdawn_native a shared library because
currently it was depending on dawncpp's definition of .Get().
