Subject: [PATCH] Add C# bindings for Errata API (#1259)

Summary:
Pull Request resolved: https://github.com/facebook/yoga/pull/1259

Wires C ABI to C# bindings using `System.Runtime.InteropServices`. Note that we don't have a working C# build right now, but there is [effort to address that](https://github.com/facebook/yoga/pull/1207) which may get some more effort before the Yoga release, so this keeps the bindings up to date.
