Context:
As part of the `test_docs_examples_ivy` job, we run 5 concurrent builds
on each VM (each for a different example/project). Additionally, all
example projects share the same `node_modules/` (via a symlink to
`aio/tools/examples/shared/node_modules/`), so all concurrent builds
operate on the same files.
Previously, we pre-ran ngcc with `--properties module` to process the
fesm5 bundles. Since we have switched to es2015 in 661a57d9e, we now
need the esm2015 bundles. As a result, the initial ngcc run is
redundant and ngcc runs again during each build (to process the fesm2015
bundles). Since there are 5 concurrent builds, we often end up with
multiple ngcc instances processing the same package and trying to write
to the same directories at the same time, causing a
`file already exists` error
This commit fixes it by pre-processing the esm2015 bundles, so there is
no need to re-run ngcc during each concurrent build.

Sometimes, in ESM5 code, aliases to exported variables are used internally
to refer to the exported value. This prevented some analysis from being
able to match up a reference to an export to the actual export itself.
For example in the following code:
```
var HttpClientXsrfModule = /** @class */ (function () {
function HttpClientXsrfModule() {
}
HttpClientXsrfModule_1 = HttpClientXsrfModule;
HttpClientXsrfModule.withOptions = function (options) {
if (options === void 0) { options = {}; }
return {
ngModule: HttpClientXsrfModule_1,
providers: [],
};
};
var HttpClientXsrfModule_1;
HttpClientXsrfModule = HttpClientXsrfModule_1 = tslib_1.__decorate([
NgModule({
providers: [],
})
], HttpClientXsrfModule);
return HttpClientXsrfModule;
}());
```
We were not able to tell that the `ngModule: HttpClientXsrfModule_1` property
assignment was actually meant to refer to the `function HttpClientXrsfModule()`
declaration. This caused the `ModuleWithProviders` processing to fail.
This commit ensures that we can compile typings files using the ESM5
format, so we can now update the examples boilerplate tool so that it
does not need to compile the ESM2015 format at all.

Now that we are using package.json properties to indicate which
entry-point format to compile, it turns out that we don't really
need to distinguish between flat and non-flat formats, unless we
are compiling `@angular/core`.

You can now specify a list of properties in the package.json that
should be considered (in order) to find the path to the format to compile.
The build marker system has been updated to store the markers in
the package.json rather than an additional external file.
Also instead of tracking the underlying bundle format that was compiled,
it now tracks the package.json property.
BREAKING CHANGE:
The `proertiesToConsider` option replaces the previous `formats` option,
which specified the final bundle format, rather than the property in the
package.json.
If you were using this option to compile only specific bundle formats,
you must now modify your usage to pass in the properties in the package.json
that map to the format that you wish to compile.
In the CLI, the `--formats` is no longer available. Instead use the
`--properties` option.

Currently when adding the example boilerplate to all
examples with Ivy enabled, we run Ngcc and transform
all found formats. This potentially slows down the build and
is not necessary as we only need the "fesm5" and "fesm2015" bundles.

File overwrites:
- **angular.json**: Add `serviceWorker: true` to production config.
- **package.json**: Add `@angular/service-worker` to dependencies.
This will make any `service-worker` examples work out-of-the-box, when
downloading and running locally from the `.zip` archives.

Examples using `@angular/elements` need to transpile to es2015 for
Custom Elements to work (on browsers that natively support them).
Alternatively, a polyfill would need to be loaded. For now, changing the
transpilation target to es2015 is the simplest solution.

The tooling for boilerplate was also running `yarn install` on the examples'
shared folder. But since this is handled by `ng-packages-installer` this
commit refactors the tools so that the boilerplate no longer does this
anymore.

This commit allows building angular.io against the locally built Angular
packages. It adds two new npm scripts:
- `setup-local`: Same as `setup`, but overwrites the Angular packages for both
angular.io and the examples boilerplate with the locally built ones.
- `build-local`: Same as `build`, but uses `setup-local` instead of `setup`
under the hood, thus overwriting installed Angular packages with locally built
ones.

With this commit `ngc` is used instead of `tsc-wrapped` for
collecting metadata and tsickle rewriting and `tsc-wrapped`
is removed from the repository.
`@angular/tsc-wrapped@5` is now deprecated and is no longer
used, updated, or maintained as part as of Angular 5.x.x.
`@angular/tsc-wrapped@4` is still maintained and required by
Angular 4.x.x and will be maintained as long as 4.x.x is in
LTS.

This commit also updates the version of `@angular/cli` used for docs examples.
The previous (transient) dependency `@ngtools/webpack` was not compatible with
`@angular/compiler-cli@>=5` and was breaking when running against the local
builds (currently at 5.0.0-beta.2). The version of `@ngtools/webpack` used by
the latest `@angular/cli` version is compatible with `@angular/compiler-cli@5`.
