Now that terser_minified supports args as of nodejs rules 0.40.0, ng_rollup_bundle can updated to the pass —comments /a^/ to args can turn off all comments and maintain the current ng_rollup_bundle behavior with the latest version fo terser. //packages/core/test/bundling/todo:bundle.min.js size test passes with this fix.
Tho not strictly necessary to update terser, this will be a rough edge when someone does try it as it is not obvious why the //packages/core/test/bundling/todo:bundle.min.js size test fails. Updating now should save time in the future by not hitting this issue.\
This change also affect ng_package output as the default comments that are preserved by terser are now Comments with @preserve, @license, @cc_on as well as comments starting with /*! and /**! are now preserved by default.. (https://github.com/terser/terser/blob/master/CHANGELOG.md). Example ng_package golden file also updated as there are not some /*! comments preserved that were in older versions of terser.

The legacy nodejs rules rollup_bundle is now deprecated and will be removed in the nodejs rules 1.0 release due in mid-November. This PR brings in the rules_nodejs internal API deps that ng_rollup_bundle, ng_package and ls_rollup_bundle depend on into this repo to break the dependency. In the future these rules should switch to use the new rollup_bundle via a macro as done in https://github.com/angular/angular/pull/33329 but this is not possible right now due to the complication of having esm5 re-rooted ts_library dependencies.
The es6 sources now have .mjs extensions so they no longer need to be re-rooted to `{package}.es6`. This eliminates the need for the collect_es6_sources() function.
Note: repo has been updated to the newest working version of rollup which is 1.25.2. There is some regression in 1.26.0 which causes the following bundling failure:

Injectable defs are not considered public API, so the property
that contains them should be prefixed with Angular's marker
for "private" ('ɵ') to discourage apps from relying on def
APIs directly.
This commit adds the prefix and shortens the name from
ngInjectableDef to "prov" (for "provider", since injector defs
are known as "inj"). This is because property names cannot
be minified by Uglify without turning on property mangling
(which most apps have turned off) and are thus size-sensitive.
PR Close#33151
Within an Angular package, it can happen that there are
entry-points which do not contain features that belong into
an `@NgModule` or need metadata files to be generated.
For example: the `cdk`, `cdk/testing` and `cdk/coercion`
entry-points. Besides other entry-points in the `cdk`
package, those entry-points do not need metadata to
be generated and no not use the `ng_module` rule.
Currently the "ng_package" rule properly picks up such
entry-points and builds bundles, does downleveling etc.
The only thing it misses is that no `package.json` files
are generated for the entry-point. This means that consumers
will not be able to use these entry-points built with "ts_library"
(except accessing the individual bundlings explicitly).
The "ng_package" rule should follow the full APF specification
for such entry-points. Partially building bundles and doing the
downleveling is confusing and a breaking issue.
The motifivation of supporting this (besides making the
rule behavior consistent; the incomplete output is not
acceptable), is that using the "ng_module" rule does
not make sense to be used for non-Angular entry-points.
Especially since it depends on Angular packages to
be specified as Bazel action inputs just to compile
vanilla TypeScript with `@angular/compiler-cli`.

BREAKING CHANGE:
Angular bazel users using protractor_web_test_suite from @angular/bazel npm package should now switch to the @bazel/protractor npm package.
This should impact very few users and the user's that are impacted have a very easy upgrade path to switch to fetching the protractor_web_test_suite rule via the @bazel/protractor npm package.

There has been a regression where enabling rollup treeshaking causes errors during runtime because it will drop const access which will always evaluate to true or false. However, such `const` in `@angular/core` cannot be dropped because their value is changed when NGCC is run on `@angular/core`

load(path) {
/** @type {?} */
const legacyOfflineMode = !ivyEnabled && this._compiler instanceof Compiler;
return legacyOfflineMode ? this.loadFactory(path) : this.loadAndCompile(path);

From the above we can see that `ivyEnabled ` is being treeshaken away when generating the FESM bundle which is causing runtime errors such as `Cannot find module './lazy/lazy.module.ngfactory'` since in Ivy we will always load the factories.

`ng_module` will now include an `src/r3_symbol.d.ts` when compiling the core package under `ngc` togather with `dts bundling`, This is due that `ngcc` relies on this file to be present, but the `r3_symbols` file which is not part of our public api.
With this change, we can now ship an addition dts file which is flattened.

This commit allows //packages/bazel/test/ngc-wrapped/... tests to run
under Ivy mode. To get them to pass, it addresses a problem with the
way the tests are configured: both test targets have sloppy .d.ts
dependencies configured, leading to many type errors being generated
in TypeScript for the .d.ts files.
Due to the way ngc directs TypeScript emit, it avoids type-checking
.d.ts files and thus this issue does not surface. ngtsc does a whole-
program emit which results in full .d.ts type-checking by default,
catching this configuration issue.
To fix this, skipLibCheck is added to the tsconfig.jsons for these
tests, which tells TypeScript to skip type-checking of the .d.ts files,
avoiding this problem in a similar way to ngc.
