[llvm] [libsycl][NFC] Suppress shadow warnings from LLVM headers (PR #225089)

[Sergey Semenov via llvm-commits]

https://github.com/sergey-semenov created https://github.com/llvm/llvm-project/pull/225089

The warning for a local variable shadowing a class member is enabled for libsycl, but not LLVM as a whole. Suppress those for included LLVM headers.
