LLVM_SYMBOLIZER_PATH is required if `llvm-symbolizer` isn't in the developer's PATH. This sets it via bazel instead of having a developer handle it. I noticed this because the apt install of clang doesn't put llvm-symbolizer in the PATH. I'd like to make this the default without putting it everywhere, but I don't see a way to do this intrinsically through [the toolchain](https://bazel.build/docs/cc-toolchain-config-reference), and the [rules_cc/defs.bzl](https://github.com/bazelbuild/rules_cc/blob/main/cc/defs.bzl) remains a thin wrapper around the native cc_binary. Since I'm adding another env, it seems undesirable to have the macos asan workaround separate. As a consequence, this merges it in. Note bazel doesn't support merging a dict and a select, so it's also necessary to have the two env vars at least mildly aware there's something up (and this could get worse if we end up having more selects).
