This patch moves `LazyDetector` and target specific (Cuda, Hip, SYCL) installation detectors to clang's include directory. It was problematic for downstream to use headers from clang's lib dir. The use of lib headers could lead to subtle errors, as some of the symbols there are annotated with `LLVM_LIBRARY_VISIBILITY`. For instance [`ROCMToolChain::getCommonDeviceLibNames`](https://github.com/jchlanda/llvm-project/blob/jakub/installation_detectors/clang/lib/Driver/ToolChains/AMDGPU.h#L147) is c++ public, but because of the annotation it ends up as ELF hidden symbol, which causes errors when accessed from another shared library.
