build: update to node v14

NodeJS v14 is the current LTS version and we should switch as the
Angular framework/dev-infra also updates to Node V14. See angular/angular#41544

We remove the engines filed in non-top-level `package.json` files to avoid
unnecessary churn. We keep NodeJS v12 working as this is the minimum
required version for framework too and diverging could cause productivity
issues when switching between projects.

 # We want to invalidate the cache if the postinstall patches change. In order to apply new
