[BUG] Simple matrix rotation could not compile

[lucifer1004]

Describe the bug
The following program could not compile:

#include "cutlass/matrix.h"

int main() {
  using Element = float;
  cutlass::Matrix<Element, 3, 3> A;
  cutlass::Matrix<Element, 3, 1> B;
  A.rotation(0.2f, B);
}

The error was

cutlass/include/cutlass/matrix.h(7828): error: class "cutlass::Matrix<float, 3, 3>" has no member "set_slice3x3"
      m.set_slice3x3({

The reason might be that set_slice3x3 renamed to set_slice_3x3 but there are still several occurrences remaining. It should be simple to fix.
