InjectionToken can be created with an ngInjectableDef, and previously
this allowed the full expressiveness of @Injectable. However, this
requires a runtime reflection system in order to generate factories
from expressed provider declarations.
Instead, this change requires scoped InjectionTokens to provide the
factory directly (likely using inject() for the arguments), bypassing
the need for a reflection system.

This commit bundles 3 important changes, with the goal of enabling tree-shaking
of services which are never injected. Ordinarily, this tree-shaking is prevented
by the existence of a hard dependency on the service by the module in which it
is declared.
Firstly, @Injectable() is modified to accept a 'scope' parameter, which points
to an @NgModule(). This reverses the dependency edge, permitting the module to
not depend on the service which it "provides".
Secondly, the runtime is modified to understand the new relationship created
above. When a module receives a request to inject a token, and cannot find that
token in its list of providers, it will then look at the token for a special
ngInjectableDef field which indicates which module the token is scoped to. If
that module happens to be in the injector, it will behave as if the token
itself was in the injector to begin with.
Thirdly, the compiler is modified to read the @Injectable() metadata and to
generate the special ngInjectableDef field as part of TS compilation, using the
PartialModules system.
Additionally, this commit adds several unit and integration tests of various
flavors to test this change.

Same fix as e70d7a2a7c
This is because the CompilerOptions needs to have directoryExists undefined in order to get the google3 behavior,
so we have to set the property outside the constructor.

Both Firefox and Safari are vulnerable to XSS if we use an inert document
created via `document.implementation.createHTMLDocument()`.
Now we check for those vulnerabilities and then use a DOMParser or XHR
strategy if needed.
Further the platform-server has its own library for parsing HTML, so we
sniff for that (by checking whether DOMParser exists) and fall back to
the standard strategy.
Thanks to @cure53 for the heads up on this issue.

The CLI app is now checked in, rather than generated dynamically with
`ng new`. This loses some assertion power, but gains hermeticity.
It also checks in lock files for all integration tests, avoiding
floating version numbers.
We'll need another place to integration test between changes in
the various repositories - but the angular/angular PR-blocking status
is not the right place to do this.

Since our version of Chromium is also pinned, a new ChromeDriver (that
drops support for our Chromium version) can cause random (and unrelated
to the corresponding changes) errors on CI.
This commit pins the version of ChromeDriver and it should now be
manually upgraded to a vrsion that is compatible with th currently used
Chromium version.

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.

We now create 2 programs with exactly the same fileNames and
exactly the same `import` / `export` declarations,
allowing TS to reuse the structure of first program
completely. When passing in an oldProgram and the files didn’t change,
TS can also reuse the old program completely.
This is possible buy adding generated files to TS
in `host.geSourceFile` via `ts.SourceFile.referencedFiles`.
This commit also:
- has a minor side effect on how we generate shared stylesheets:
- previously every import in a stylesheet would generate a new
`.ngstyles.ts` file.
- now, we only generate 1 `.ngstyles.ts` file per entry in `@Component.styleUrls`.
This was required as we need to be able to determine the program files
without loading the resources (which can be async).
- makes all angular related methods in `CompilerHost`
optional, allowing to just use a regular `ts.CompilerHost` as `CompilerHost`.
- simplifies the logic around `Compiler.analyzeNgModules` by introducing `NgAnalyzedFile`.
