Another step toward #11638
This PR is a continuation of #12732.
There were BLAS calls in the following cython files:
weight_vector.pyx,cd_fast.pyxand_k_means.pyx.There were also BLAS calls in the C file
cholesky_delete.h. I decided to move (using fused types) the only function there to cython inarrayfuncs.pyxwhere there was a python wrapper for it.I added
rotanrotgto the cython blas functions which I forgot in [MRG] Use Scipy cython BLAS API instead of bundled CBLAS #12732 because I didn't check C files...I also removed linking to blas libs in some setups for modules which didn't call BLAS functions.
The only remaining calls to bundled CBLAS in sklearn appear in
tron.cpp, used in liblinear. They can't be replaced easily by calls to scipy cython blas because the calls to BLAS are not from cython files but from C files.
