pw_rust_crates_extension allows the pigweed modules "rust_crates" repo to
be overridden using https://bazel.build/rules/lib/globals/module#override_repo

Downstream projects needing to provide a local `rust_crates` repo can
do so by adding the following to their root MODULE.bazel


local_repository(name = "rust_crates", path = "build/crates_io")

pw_rust_crates = use_extension("@pigweed//pw_build:pw_rust_crates_extension.bzl", "pw_rust_crates_extension")
override_repo(pw_rust_crates, rust_crates = "rust_crates")
