utils: Add llvm-symbolizer to install_components_with_clang presets

llvm-symbolizer is critical to ASAN/LSAN properly reading and applying
allowlists and suppressions. Without properly symbolized backtraces,
the tools cannot match stack traces to suppression lists, leading to
false negatives in leak detection and other issues.

Ensure that it's installed in the toolchain presets.
