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`.

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`

const SWITCH_IVY_ENABLED__POST_R3__ = true;
const SWITCH_IVY_ENABLED__PRE_R3__ = false;

Ivy (After NGCC)

const ivyEnabled = SWITCH_IVY_ENABLED__POST_R3__;

FESM2015
```
load(path) {
/** @type {?} */
const legacyOfflineMode = this._compiler instanceof Compiler;
return legacyOfflineMode ? this.loadFactory(path) : this.loadAndCompile(path);
}
```
ESM2015
```
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.

ngtsc now produces flat module index files when that option is enabled
in tsconfig, but Bazel still needs the output declared in order for them to
be passed through.
This fixes some tests which verify this behavior on Bazel.

* No longer depends on a custom CircleCI docker image that comes with Bazel pre-installed. Since Bazel is now available through NPM, we should be able to use the version from `@bazel/bazel` in order to enforce a consistent environment on CI and locally.
* This also reduces the amount of packages that need to be published (ngcontainer is removed)

We are close enough to blacklist a few test targets, rather than whitelist targets to run...
Because bazel rules can be composed of other rules that don't inherit tags automatically,
I had to explicitly mark all of our ts_library and ng_module targes with "ivy-local" and
"ivy-jit" tags so that we can create a query that excludes all fixme- tagged targets even
if those targets are composed of other targets that don't inherit this tag.
This is the updated overview of ivy related bazel tags:
- ivy-only: target that builds or runs only under ivy
- fixme-ivy-jit: target that doesn't yet build or run under ivy with --compile=jit
- fixme-ivy-local: target that doesn't yet build or run under ivy with --compile=local
- no-ivy-jit: target that is not intended to build or run under ivy with --compile=jit
- no-ivy-local: target that is not intended to build or run under ivy with --compile=local
