Subject: src: stop using deprecated fields of `v8::FastApiCallbackOptions`

Two fields on the `v8::FastApiCallbackOptions` struct were deprecated
recently: `fallback` and `wasm_memory`. This PR removes uses of these
two fields in node.js.

(This is a subset of upstream commit d0000b118 from the `canary-base`
branch of Node.js. This patch can be removed when Electron upgrades to
a stable Node release that contains the change. -- Charles)
