  [clang-sycl-linker] Decouple link step from SYCL; adopt -L / --bc-library options (#199777)

The bitcode link phase in `clang-sycl-linker` is not SYCL-specific — it
  links input bitcode, then links library bitcode with `LinkOnlyNeeded`.
  This PR makes the implementation reflect that and aligns the option
  surface with `clang-nvlink-wrapper`.

  - Rename `linkDeviceCode` / `getSYCLDeviceLibs` and strip SYCL/device
    wording from verbose output, errors, and doc-comments. The
    `runSYCLLink` doc-comment is expanded to describe the full
    link → split → codegen → AOT → pack pipeline it actually drives.
  - Replace `--device-libs=a.bc,b.bc` with repeatable `--bc-library`,
    resolved against `-L` search paths. `-L` becomes the canonical form;
    `--library-path` / `--library-path=` are kept as hidden aliases and
    now accumulate (previously last-wins).
  - Consolidate the four `Inputs/SYCL/*.ll` fixtures and
`link-device-code.test` into one `split-file`-based `link.ll`; refresh
    affected check prefixes. New checks cover `-L` joined form,
    multi-`-L` fall-through, and first-match-wins ordering.
- ClangSYCLLinker.rst got a substantive refresh beyond doc-comments:
intro paragraphs rewritten, help-text block updated, dropped options
(-g,
-is-windows-msvc-env, -llvm-spirv-options=, --llvm-spirv-path=) and
added options (--module-split-mode, --ocloc-options,
--opencl-aot-options) so the doc
  matches current .td reality.
