We should add an async `getEIP1559Compatibility` method that populates the `networkDetails` (aka `properties`) state if it's not set yet. This is useful in cases where other parts of the codebase need to guarantee this state is set before proceeding. This is part of [a larger effort to normalize the API of both network controllers](https://github.com/MetaMask/controllers/issues/971), to make them easier to merge.
