fix(toolchains): Add Xcode repo env vars to local_runtime_repo for better cache invalidation (#3203)

On macOS, if one writes a `local_runtime_repo` with `interpreter_path =
"/usr/bin/python3"`, the path to python3 inside the selected
_Xcode.app/Contents/Developer_ directory gets cached. If a developer
changes that directory with `xcode-select --switch` that cached file
with the old directory remains.

Making the local_runtime_repo rule sensitive to DEVELOPER_DIR and
XCODE_VERSION (two conventionally adopted env vars among the Bazel +
Apple ecosystem) will ensure that if Xcode changes, so will the resolved
python3 path.

Fixes #3123
