  [clang-sycl-linker] Make temp files land relative to cwd with unique names (#224506)

Derive the CodeGen/AOT stem from -o's basename instead of its full
path, so these intermediates land in cwd alongside the .bc temps
instead of splitting -save-temps output across two directories.

Route them through createTempFile instead of building
`<stem>_<index>.ext` directly, so parallel invocations sharing an
output basename don't collide. Its random suffix also makes
`_<index>` redundant, so drop it; `--spirv-dump-device-code` keeps its
index since it has no random suffix and still needs one.
