Description

The current svd method in kornia-linalg only support fp32, which is limiting for crates such as konira-icp and kornia-pnp that requires fp64 support.

Contributor guide

Research direction
Investigate the current svd3 implementation in kornia linalg to understand its type constraints (likely using nalgebra or similar). Then add support for f64 by either making the function generic over the scalar type or by adding an additional implementation for f64. Check if there are any dependencies on fp32 specific functions that need to be replicated or made generic. Also consider performance implications for f64 operations.
