This patch moves `clang/tools/clang-linker-wrapper/OffloadWrapper.*` to `llvm/Frontend/Offloading` allowing them to be re-utilized by other projects. Additionally, it makes minor modifications to the API to make it more flexible. Concretely: - The `wrap*` methods now have additional arguments `EntryArray`, `Suffix` and `EmitSurfacesAndTextures` to specify some additional options. - The `EntryArray` is now constructed by the caller. This change is needed to enable JIT compilation, as ORC doesn't fully support `__start_` and `__stop_` symbols. Thus, to JIT the code, the `EntryArray` has to be constructed explicitly in the IR. - The `Suffix` field is used when emitting the descriptor, registration methods, etc, to make them more readable. It is empty by default. - The `EmitSurfacesAndTextures` field controls whether to emit surface and texture registration code, as those functions were removed from `CUDART` in CUDA 12. It is true by default. - The function `getOffloadingEntryInitializer` was added to help create the `EntryArray`, as it returns the constant initializer and not a global variable.
