[Consistency] Default behaviour of SVD vs QR

See original GitHub issue

Problem The current default behaviour of linalg.svd computes the full decomposition by setting full_matrices=True by default. On the other hand, the default behaviour of linalg.qr specifies mode="reduced" by default.

Proposal Change de default to full_matrices=False in linalg.svd. In most cases the reduced SVD is good enough. Even more, it’s better to do less work by default and just make the more expensive operation opt-in.

Yeah we don’t even have full_matrices=True as an option in Dask currently. It is implemented as full_matrices=False. Though we do have an open issue about adding this ( https://github.com/dask/dask/issues/3576 )
