  [libc] Fix GPU fatbinary dependencies for multi-source object libraries

Summary:
Multi-source object libraries require some additional handling, this
logic wasn't correctly settending the dependency on each filename
individually and was instead using the last one. This meant that only
the last file was built for multi-object libraries.

  [libc] Fix CMake deduplication `-Xclang` arguments

Summary:
We use `-Xclang` to pass the GPU binary to be embedded. In the case of
multi-source objects this will be passed more than once, but CMake
implicitly deduplicates arguments. Use the special generator to prevent
this from happening.
