Summary:
X-link: https://github.com/facebook/react-native/pull/43299

Add the React Clang Tidy config to Yoga, run the auto fixes (with some mechanical manual tweaks). Notably, the automatic changes to the infra for generating a Yoga tree from JSON capture make it 70% faster.

Before:
{F1463947076}

After:
{F1463946802}

This also cleans up all the no-op shallow const parameters in headers.

{F1463943386}

Not all checks are available in all environments, but that is okay, as Clang Tidy will gracefully skip them.
