[lld] [libc] [clang-tools-extra] [clang] [lldb] [llvm] [libcxx] [compiler-rt] [openmp] [flang] Gcc 75 libomptarget type convert (PR #75562)

[via llvm-commits]

https://github.com/SunilKuravinakop created https://github.com/llvm/llvm-project/pull/75562

When building with gcc-7.5 we get the error:
`nochange/openmp/libomptarget/src/PluginManager.cpp: In static member function 'static llvm::Expected<std::unique_ptr<PluginAdaptorTy> > PluginAdaptorTy::create(const string&)':
`
To overcome this an std::move has been added to convert from 
`std::unique_ptr<PluginAdaptorTy> to Expected<std::unique_ptr<PluginAdaptorTy>>`
This problem does not occur in higher versions of the compiler like gcc-12.2
