Subject: [PATCH] Export `LayoutResults::operator==`

Summary:
X-link: https://github.com/react/react-native/pull/59997

`yoga::Node` is exported from the Yoga library and hands out its `LayoutResults` through `getLayout()`, but `LayoutResults::operator==` is defined out of line and not exported. Code outside Yoga that compares two layout results fails to link wherever Yoga is built as a shared library with hidden visibility.

Mark the operator `YG_EXPORT` so React Native can compare a node's layout results with those of the node it replaces.
