a0fe8bbd - [OpenMP][OMPD] Set plugin RUNPATH to identify LLVM Libs (#223691)

[OpenMP][OMPD] Set plugin RUNPATH to identify LLVM Libs (#223691) `ompdModule` links LLVMSupport, but GDB loads it from `share/gdb/python/ompd/ompdModule.so` while LLVM libs lives in `lib/LLVMSupport.so` or `lib/LLVM.so`. The dynamic linker (one that opens .so files) loosk at: 1) paths inside .so (aka RUNPATH) 2) `LD_LIBRARY_PATH` 3) or system defaults paths After [previous patch](https://github.com/llvm/llvm-project/pull/222455), a normal install can fail with "cannot open shared object file" unless the user sets `LD_LIBRARY_PATH` by hand which is easy to forget after `ninja install`. Fix: The approach is to make CMake write RUNPATH on `ompdModule.so`, so the plugin follows its own directions and hence the linker (same approach LLDB uses for its Python module). This completes the LLVM link added in the previous patch. It does not change how `libompd.so` is located (still `ompd_dll_locations`/`LD_LIBRARY_PATH`).
