Currently, in the RTTI Builder vTableClassNameForType, we return the VTable Class name for each type. This task's scope is to complete the support for the NYI types and add a test for that.

• In the VTableClassNameForType function, check branches with NYI error and choose one type.
• Find and return the correct VTableClass name, either from the ClangIR repository or the classical codegen.
• Write a test that emits RTTI for that type (Hint: One way is to throw expr with that type).

Notes:

• Please mention what type you will work on in this issue.
• Please keep it one PR per type.
• Check Throws.cpp and CIRGenItaniumCXXAPI.cpp changes for reference in [CIR] ThrowOp with Complex type as Subexpr #163078.
• If the type is handled by you, see no test for it, feel free to add one.
