cupyx.scipy.sparse.linalg and scipy.sparse.linalg

[jbeuria]

Description

scipy.sparse.linalg contains several matrix operations such as expm, inv, expm_multiply, etc. Can these be implemented in cupy. In real scenarios we encounter sparse matrices. It would be great to have them in cupy. Meanwhile, are there any alternative ways to do it?

I'll be happy to work on these when I get up to speed, to catch up I have #8305 opened.
