Description
Currently, the cholesky requires you to have LayoutLeft for the sake of CUBLAS requiring it. This is somewhat irritating because the OpenMP backend of kokkos has a default layout of LayoutRight, so when I sample with the Gaussian distribution, I have to call the SampleImpl function directly, lest I want to get a runtime error that says I'm trying to use an incompatible LayoutRight View (i.e. I can't use the default Layout for Views when interacting with the Cholesky, namely within the Gaussian distribution).

Research direction
Start by tracing the Cholesky layout requirements and its CUBLAS interaction, then compare them with the OpenMP backend's default LayoutRight behavior. Done means Gaussian sampling can use the default LayoutRight View with Cholesky without calling SampleImpl directly or triggering an incompatible-layout runtime error.
