Revert "Undo a rearchitecture that breaks us downstream (#777)"

[Saadnajmi]

This reverts commit 73224cf, which itself was a revert of a commit. So we're bringing back the original change.

We thought it would break things downstream for us, but are electing to instead fix things downstream rather than undo this commit.

Please select one of the following

• I am removing an existing difference between facebook/react-native and microsoft/react-native-macos 👍
• I am cherry-picking a change from Facebook's react-native into microsoft/react-native-macos 👍
• I am making a fix / change for the macOS implementation of react-native
• I am making a change required for Microsoft usage of react-native
