I don't think we should remove all instances of RWBuffer in testing. Although
we plan to eventually move all hlsl resources into an appropriate header, with
the corresponding spellable hlsl attributes, as it stands now RWBuffer is
defined in HLSLExternalSemaSource.cpp within a template specialization decl.
There is code in this change that specifically accounts for this, and by
removing RWBuffer entirely from the tests, it would become dead code.
Specifically, `getSpecifiedHLSLAttrFromRecordDecl` has an if condition to check
if the record decl is a `ClassTemplateSpecializationDecl`, which is only the
case for types declared in HLSLExternalSemaSource.cpp.
This change should test both user defined types that have the spellable
attribute of interest, but ideally the end goal is that it works with actual
practical HLSL resources, like RWBuffer.
