------------------------------+---------------------------------------------
This patch primarily moves the code for the Cholesky decomposition up to
the "matrix double dense" module, where it belongs, and is consistent with
the approach for other decompositions. The !SciPy code is general enough
to handle RDF/CDF symmetric/Hermitian cases simultaneously so the move is
easy.
Side-effects:
* Significant documentation upgrade.
* No doctest in matrix2 needs adjustment due to the code change here.
* First step in un-deprecating the `cholesky()` method.
The `cholesky_decomposition()`, `_cholesky_decomposition()` situation is a
'''total mess''' and needs fixing. The shorter name is more consistent
with others, such as `schur()` and `SVD()`. Once the exact version of
`cholesky()` is concluded at #11274, then I plan to get the mess all
straightened out. This patch is independent of the ones for the exact
matrices, so has no dependencies.
