[bindings] Use |PostMessage| attribute for DedicatedWorkerGlobalScope.postMessage to eliminate custom bindings

As the code is using the binding code generator for the |postMessage|, the interfaceName is derived from the
|interface_name|. To align to this scheme, the layout tests have been modified to receive the exception object
with interface name as the |interface_name|.

PTAL, thanks.

PS: For the context, the CL [1] has introduced |PostMessage| IDL extended
attribute to auto-generate the code required for interfaces using |postMessage|
method. In doing so, the bindings template generator uses |interface_name| while
creating the ExceptionState object here [2]. Due to this auto-generation, we
need to rename the Exception interface names from WorkerGlobalScope to
DedicatedWorkerGlobalScope.

WDYT?

From the perspective of bindings, this looks good.

LGTM but let's wait for worker guy's approval.

Yes definitely as this is user facing change.

LGTM, nice that we can now get rid of the custom code.
