Rollup merge of #118142 - saethlin:llvm-linkage, r=tmiasko

Tighten up link attributes for llvm-wrapper bindings

Fixes https://github.com/rust-lang/rust/issues/118084 by moving all of the declarations of symbols from `llvm_rust` into a separate extern block with `#[link(name = "llvm-wrapper", kind = "static")]`.

This also renames `LLVMTimeTraceProfiler*` to `LLVMRustTimeTraceProfiler*` because those are functions from `llvm_rust`.
