[pointer_interceptor] Remove implements from app-facing package (flutter#6699)

Dart unit tests started failing for `pointer_interceptor` due to the `implements` tag in the app facing package. This plugin is federated for ios and web, so it looks like the error message is valid.

```
Plugin pointer_interceptor:ios provides an implementation for pointer_interceptor_platform_interface and also references a default implementation for pointer_interceptor_ios, which is currently not supported. Ask the maintainers of pointer_interceptor to either remove the implementation via `implements: pointer_interceptor_platform_interface` or avoid referencing a default implementation via `platforms: ios: default_package: pointer_interceptor_ios`.

This removes the tag and does a manual roll.
