docs: deprecate @angular-devkit/build-optimizer (#43915)

The entire package is deprecated in v13. Deprecation message is mostly copied from the package's [README](https://github.com/angular/angular-cli/blob/13.0.0-next.9/packages/angular_devkit/build_optimizer/README.md), with just some minor edits.

(cherry picked from commit d81744e600)

### @angular-devkit/build-optimizer
The entire NPM package is deprecated. It has always been experimental (never hit `1.0.0`) and has
