[NFC][clang-sycl-linker] Avoid ambiguous call to CallingConv

[jsji]

both llvm and clang namespace have CallingConv.
Add namespace prefix to avoid ambiguous call .

[Copilot]

Pull Request Overview

This PR resolves a namespace ambiguity issue in the clang-sycl-linker where CallingConv exists in both the llvm and clang namespaces. The change explicitly prefixes all CallingConv references with the llvm:: namespace to eliminate the ambiguous call.

• Adds explicit llvm:: namespace prefix to CallingConv references
• Resolves compilation ambiguity between llvm::CallingConv and clang::CallingConv
