targets/rp2040: Link software atomic operations
This links in pw_atomic's software implementations of atomic operations
into the RP2040 target builds. These will be required by a future
pw_metric update.
This isn't required in the Bazel build as it already pulls in the Pico
SDK, which provides atomics.
