This introduces the cir.delete_array operation, adds code to emit that operation during CIR codegen, and adds lowering of the operation to the CXXABILowering pass. In order to handle possible variations in the delete representation, we add the name of the delete function, the usual delete parameters, and, optionally, the name of the element destructor function. During the CXXABILoweringPass, the cir.delete_array operation is expanded to call the delete function. This will be extended in a future change to handle reading the array cookie, if required, and calling element destructors.
