refactor: migrate analytics collector to use GA4

This change updates the analytics collector collector to use GA4 instead of UA. The motivation behind this change is that UA will stop collecting data in 2023.

BREAKING CHANGE:

`analyticsSharing` option in the global angular configuration has been
removed without replacement. This option was used to configure the Angular CLI to  access to your own users' CLI usage data.

If this option is used, it can be removed using `ng config --global cli.analyticsSharing undefined`.

-# Operating System and Node Version
-
-A User Agent string is built to "fool" Google Analytics into reading the Operating System and
-version fields from it. The base dimensions are used for those.
-
-Node version is our App ID, but a dimension is also used to get the numeric MAJOR.MINOR of node.

-# Debugging
-
-Using `DEBUG=ng:analytics` will report additional information regarding initialization and
-decisions made during the usage analytics process, e.g. if the user has analytics disabled.
-
-Using `DEBUG=ng:analytics:command` will show the decisions made by the command runner.
-
-Using `DEBUG=ng:analytics:log` will show what we actually send to GA.
+## Debugging
 
-See [the `debug` NPM library](https://www.npmjs.com/package/debug) for more information.
+Using `NG_DEBUG=1` will enable Google Analytics debug mode, To view the debug events, in Google Analytics go to `Configure > DebugView`.
