Auto merge of #130040 - onur-ozkan:llvm-tools-with-ci-rustc, r=Kobzol

unify `llvm-bitcode-linker`, `wasm-component-ld` and llvm-tools logics

To use the precompiled `ci-rustc` in CI, we need to install `llvm-bitcode-linker` and LLVM tools into ci-rustc's sysroot. Without them some CI pipelines may fail, as shown [here](rust-lang/rust#122709 (comment)).

Blocker for rust-lang/rust#122709
