This splits out row/col/updateRow/updateColumn to their own file, as Data/Matrix/Basic is getting rather large.

There are no new lemmas in this PR, nor were any existing lemmas deleted.

It's possible that even more lemmas could migrate to this new file (for instance, flipping the import with Matrix.Notation or LinearAlgebra.Matrix.Trace), but I've taken the conservative option of leaving those lemmas alone for now.
