fix(runtime-core): expose events to props for functional components

[blake-newman]

Expose events to props for consumer of components to be correctly typed, onX handlers where not exposed as such the interface for functional components is incorrect for consuming FunctionalComponents in parent components.

Before:

const Foo: FunctionalComponent<{}, { change(): void }> = () => {}
// type error: Property 'onChange' does not exist on type '...'
<Foo onChange={() => {}} />

After:

const Foo: FunctionalComponent<{}, { change(): void }> = () => {}

// No type error:
<Foo onChange={() => {}} />
