bazel: Partial revert of http://pwrev.dev/226007

Revert the changes to the keys in the dicts in
targets/rp2040/transition.bzl. Changing what strings appear as keys
leads to issues in downstream projects that rely on overriding them.

We still need to remove these "@Pigweed" string instances, but need to
tread more carefully. Will update the bug with ideas.

NO_IFTTT=The values of the flags are not changed.
