This shortens Mathlib.LinearAlgebra.Basic, which is both longer than we like and doesn't have a clear scope.

The motivation is that [Mathlib/LinearAlgebra/Basic.lean](https://github.com/leanprover-community/mathlib4/pull/10233/files#diff-6f14283bfbc75a32a870660bc104a4b628a3645bacef2d02343637199a25f517) is huge? It seems like a very good idea to me.

What explains the +170 new lines? Not just a copyright header and module docstring, right?

Yes, exactly. Clarified in the summary.

It's the sections and variable lines and the empty lines between them, which I copied directly from LinearAlgebra.Basic. (I guess those are a mathport artefact? I wouldn't mind condensing them a bit.)
