  [CIR] Derive lowering attr names from cppClassName, not the def name (#220891)

CIRLoweringEmitter built its CXX_ABI_ALWAYS_LEGAL_ATTRS entries with
GetOpCppClassName, which splits the TableGen def name at the first
underscore. That works only while every def is named
CIR_<CppClassName>Attr.
When one is not, the emitter writes an `isa<>` for a class that does not
exist, and the failure lands as a compile error in generated code.

Attributes carry the authoritative name in cppClassName, which
GenerateAttrToValueVisitor was already reading. Factor that out as
GetAttrCppClassRef and use it for both attribute paths.
GetOpCppClassName
stays for operations.
