add fallback to finite diff Jacobian

[BenWibking]

In the Rosenbrock integrator, add a fall back to the FD Jacobian if the analytic Jacobian produces a NaN or Inf value.

Fixes #2007.

@zingale Fixed to use isnan/isinf.

Shouldn't it use amrex::Gpu::isnan()

Shouldn't it use amrex::Gpu::isnan()

Why? We use std::isnan in my places in device kernels in our code. I haven't seen any problems.

[zingale]

it looks like it only matters with SYCL

[zingale]

can you fix the tabs?

[BenWibking]

@zingale tabs fixed.
