build(bazel): Use local rollup & build-optimizer for ng_rollup_bundle (#28215)

The current build workflow depends on cross workspace dependency by
installing angular-cli as a Bazel repository. This is not ideal because
it introduces separate node_module directories other than the one
installed by Angular through the yarn_install rule (ngdeps).

This commit removes angular-cli from the Bazel workspace and installs
rollup and @angular-devkit/build-optimizer locally.
