Debug version matrix.c

This matrix.c is quantum/matrix.c with the following additions:

  • Added the MATRIX_DEBUG_SCAN_{START/END} macro to measure the execution time of matrix_scan().
  • Added the MATRIX_DEBUG_DELAY_{START/END} macro to measure delay time.
  • Added the MATRIX_MUL_SELECT handling for symmetric70_proto.
