Args:
ukernel: C name of the micro-kernel function.
op_type: Operation type (MAX/MIN/SUM/etc).
init_fn: C name of the function to initialize microkernel parameters.
requantization_type: Requantization type (FP32/RNDNU).
tester: C++ name of the tester class.
batch_tile: Number of batch elements processed per one iteration of the
inner loop of the micro-kernel.
vector_tile: Indicates if batch tile is specified in vectors rather than

isa: instruction set required to run the micro-kernel. Generated unit test
will skip execution if the host processor doesn't support this ISA.
