add crot and zrot to LAPACKE

[kevinsung]

Description

Fixes #962.

I tested this by creating a file

/* test_rot.c */
#include <lapacke.h>
#include <stdio.h>

int main() {
    lapack_complex_float  cx = lapack_make_complex_float(1.0f, 0.0f);
    lapack_complex_float  cy = lapack_make_complex_float(0.0f, 1.0f);
    lapack_complex_float  cs = lapack_make_complex_float(0.0f, 1.0f);
    lapack_complex_double zx = lapack_make_complex_double(1.0, 0.0);
    lapack_complex_double zy = lapack_make_complex_double(0.0, 1.0);
    lapack_complex_double zs = lapack_make_complex_double(0.0, 1.0);

    LAPACKE_crot(1, &cx, 1, &cy, 1, 0.0f, cs);
    LAPACKE_zrot(1, &zx, 1, &zy, 1, 0.0,  zs);
    printf("crot and zrot succeeded\n");
    return 0;
}

and then running

mkdir build
pushd build
cmake .. -DLAPACKE=ON -DBUILD_TESTING=ON
cmake --build . --target lapacke -j$(nproc)
popd
gcc -o test_rot test_rot.c -I LAPACKE/include -I build/include \
    -L build/lib -llapacke -llapack -lblas -lm && ./test_rot
