This also changes the local_runtime_repo to explicitly check for supported platforms instead of relying on a `None` value returned by the helper method. This makes the behaviour exactly the same to the behaviour before this PR and we can potentially drop the need for the validation in the future if our local_runtime detection is more robust. This also makes the platform detectino in `pypi_repo_utils` not depend on `uname` and only use the `repository_ctx`. Apparently the `module_ctx.watch` throws an error if one attempts to watch files on the system (this is left for `repository_rule` it seems and one can only do `module_ctx.watch` on files within the current workspace. This was surprising, but could have been worked around by just unifying code. This splits out things from bazel-contrib#2059 and makes the code more succinct. Work towards bazel-contrib#260, bazel-contrib#1105, bazel-contrib#1868.

You can just remove this block; as mentioned in the originating PR, I just had it return None because I knew there were cases it didn't handle, but didn't know what they were. Now that it handles all the cases, we can just assume whatever value is returned is correct.

How about _get_platforms_cpu_name instead? Since it's mapping the value to the @platforms//cpu:<name>, where the term is "cpu", not "arch".
