Define: _OPENMP -> AMREX_USE_OMP (#1520)
* Define: _OPENMP -> AMREX_USE_OMP
Replace the define check of `_OPENMP` with the explicit
backend control of `AMREX_USE_OMP` for parallel constructs.
Doing so avoids that we accidentially turn on OpenMP, e.g. if a dependency
pulls it in for linear algebra, I/O, etc. This can led to confusion if the
user explicitly requested a serial build. Also, we might want to use OpenMP
functionality here and there for auxiliary functions w/o having to use the
AMReX OpenMP backend, i.e. because we compile for GPUs.
* Add missing amrex::Gpu::notInLaunchRegion
