Expose netlifyFunction params as netlifyFunctionParams

Expose event and context of Netlify Function in Next.js pages and API
routes as `netlifyFunctionParams` (rather than `netlifyFunction`).
The new name is clearer, since we're just making the parameters of the
function available and not the function itself.
