Rollup merge of #127654 - nikic:llvm-ndebug-fix, r=cuviper
Fix incorrect NDEBUG handling in LLVM bindings

We currently compile our LLVM bindings using `-DNDEBUG` if debuginfo for LLVM is disabled. However, `NDEBUG` doesn't have any relation to debuginfo, it controls whether assertions are enabled.

Split the LLVM_NDEBUG environment variable into two, so that assertions and debuginfo are controlled independently.

After this change, `LLVMRustDIBuilderInsertDeclareAtEnd` triggers an assertion failure on LLVM 19 due to an incorrect cast. Fix it by removing the unused return value entirely.
