Specifying a kernel with the `ptx_kernel` or `amdgpu_kernel` calling convention is a more idiomatic and compile-time performant than using the `nvvm.annoation !"kernel"` metadata. Transition OMPIRBuilder to use calling conventions for PTX kernels and no longer emit `nvvm.annoation`. Update OpenMPOpt to work with kernels specified via calling convention as well as metadata. Update OpenMP tests to use the calling conventions.
