This patch renames the `OpenMPIRBuilderConfig` flags to reduce confusion over their meaning. `IsTargetCodegen` becomes `IsGPU`, whereas `IsEmbedded` becomes `IsTargetDevice`. The `-fopenmp-is-device` compiler option is also renamed to `-fopenmp-is-target-device` and the `omp.is_device` MLIR attribute is renamed to `omp.is_target_device`. Getters and setters of all these renamed properties are also updated accordingly. Many unit tests have been updated to use the new names, but an alias for the `-fopenmp-is-device` option is created so that external programs do not stop working after the name change. `IsGPU` is set when the target triple is AMDGCN or NVIDIA PTX, and it is only valid if `IsTargetDevice` is specified as well. `IsTargetDevice` is set by the `-fopenmp-is-target-device` compiler frontend option, which is only added to the OpenMP device invocation for offloading-enabled programs.
