fix(ngcc): rename the executable from ivy-ngcc to ngcc (#33140)

Previously, the executable for the Angular Compatibility Compiler
(`ngcc`) was called `ivy-ngcc`. This would be confusing for users not
familiar with our internal terminology, especially given that we call it
`ngcc` in all our docs and presentations.

This commit renames the executable to `ngcc` and replaces `ivy-ngcc`
with a script that errors with an informative message (prompting the
user to use `ngcc` instead).
