Merge branch 'cleanup-coffeescripts-from-gitlab-ci' into 'master'

Clean up coffeescript files imported from GitLab CI

## What does this MR do?

This MR cleans up CoffeeScript files imported from GitLab CI along with a strategy #19159. Some files should have been removed in !1987.

## Are there points in the code the reviewer needs to double check?

While I think the `Build` module should be named as `Build`, not `CiBuild` in the JavaScript namespace, please check if it should.

## Why was this MR needed?

Removing unused coffeescript files reduces time to build JS and so time to transfer even in production. The fewer files, the better, too.

## What are the relevant issue numbers?

Closes #19159

## Screenshots (if relevant)

n/a
