This cleans up the platforms package from dependencies that are not strictly needed. This is in preparation of making this package a separate module, which can be shared by plugins, and containerd versions (as well as external consumers), - Remove dependency on the errdefs package: most uses of these error definitions were used internally, and other errors may not be useful for external consumers as sentinel errors. - ErrInvalidArgument may be a potential exception, although a look at current uses of this package shows that there's no special handling of invalid parameters vs other errors (all would boil down to "the passed platform is invalid" (either the format, or parsing is not implemented on a specific platform) - Remove uses of the convenience "Platform" alias in favor of using the upstream (from OCI spec). Consumers of this package can still use the convenience alias, but make sure that function signatures do not imply that it's a different type (which can cause confusion).
