Remove committed `node_modules` from platforms

[raphinesse]

We don't need them anymore since CLI installs all dependencies properly now. Not having to bundle dependencies vastly simplifies adding a new dependency if you need it for a feature.

Tooling and core plugins are not affected.

Task List

• cordova-android
• cordova-browser
• cordova-ios
• cordova-osx
• cordova-windows
• cordova-coho release docs

(Added "Cordova coho Release Process documentation" as task)

For apache/cordova-ios#388, conflicts needs to be resolved and should be OK for merging since I last reviewed it. Would like a second opinion.

[erisu]

It seems apache/cordova-osx#49, covers removing the node_modules and many other smaller tasks.

• Could the node_module and bundledDependencies removal be cherry-picked?
• Is it ideal to break down this PR into smaller multiple PRs?
