Rules executed by bazel don't necessarily have the right environment to find the symbolizer, which was the intent of `cc_env` setting `LLVM_SYMBOLIZER_PATH`. So far, this has kind of been a case-by-case fix, but every so often I'm trying to debug a crash in a test that doesn't provide it. Rather continuing down this route, instead add drop-in wrappers for cc rules so that it's hard to forget. Note `bazel/cc_rules` is intended to mirror `bazel/carbon_rules` and `bazel/cc_toolchains`, rather than `@rules_cc`. AFAICT there isn't a great way to add this as a default for the `bazel run` environment. It's not typically going to be set on its own, forwarding `$PATH` would be too broad, and the [action `env_sets`](https://bazel.build/docs/cc-toolchain-config-reference#using-action-config) I think are not quite what we need (I think those don't include output execution, only compilation).
