[clang] [NFC][Clang] Make GetSDLFromOffloadArchive and SDLSearch static (PR #70201)

[Juan Manuel Martinez Caamaño via cfe-commits]

https://github.com/jmmartinez created https://github.com/llvm/llvm-project/pull/70201

Make GetSDLFromOffloadArchive and SDLSearch functions static since they are used only in the file where they are defined. The aim is to ease refactoring/modifying the declarations of these functions in the future.
