/**
 * Polyfill for the nullish coalescing operator (`??`), when used in situations where at least one of the values is the
 * result of an async operation.
 *
 * Note that the RHS is wrapped in a function so that if it's a computed value, that evaluation won't happen unless the
 * LHS evaluates to a nullish value, to mimic the operator's short-circuiting behavior.
 *
 * Adapted from Sucrase (https://github.com/alangpierce/sucrase)
 *
 * @param lhs The value of the expression to the left of the `??`
 * @param rhsFn A function returning the value of the expression to the right of the `??`
 * @returns The LHS value, unless it's `null` or `undefined`, in which case, the RHS value
