wpcom block editor: add missing wp deps

[simison]

Adds missing core dependencies in wpcom-block-editor module.

I noticed files in Calypso's /apps/wpcom-block-editor/src/common and /apps/wpcom-block-editor/src/calypso are importing from some core deps that weren't listed as dependencies in PHP side.

In practise these get enqueued in the editor currently anyway so nothing should change per-se. :-) It's just good practice and safer.

Common script was missing these

• jquery (#)
• wp-blocks (#)
• wp-dom-ready (#)
• wp-nux (#)
• wp-plugins (#)

Added to both common- and calypso-scripts

• wp-polyfill — build process doesn't include Babel/polyfill for these files so to make sure things work in IE11, you'll need to ensure it's enqueued.

Changes proposed in this Pull Request:

• Adds wp core deps

Testing instructions:

Open the block editor both in Jetpack self hosted's wp-admin as well via Calypso and confirm that everything still works as expected.

We could run the build with the extern plugin and grab the deps.json for these files to validate the dependencies.

I wonder if the dependencies should be committed on WPCOM and synced to Jetpack 🤔

[simison]

On .com these are part of a separate gutenberg-wpcom plugin which is not synced with Jetpack.
