TypeScript introduced a new flag called `noImplicitOverride` as part
of TypeScript v4.3. This flag introduces a new keyword called `override`
that can be applied to members which override declarations from a base
class. This helps with code health as TS will report an error if e.g.
the base class changes the method name but the override would still
have the old method name. Similarly, if the base class removes the method
completely, TS would complain that the memeber with `override` no longer
overrides any method.
A similar concept applies to abstract methods, with the exception that
TypeScript's builtin `noImplicitOverride` option does not flag members
which are implemented as part of an abstract class. We want to enforce
this as a best-practice in the repository as adding `override` to such
implemented members will cause TS to complain if an abstract member is
removed, but still implemented by derived classes.

For quite a while it is an unspoken convention to add a trailing
new-line files within the Angular repository. This was never enforced
automatically, but has been frequently raised in pull requests through
manual review. This commit sets up a lint rule so that this is
"officially" enforced and doesn't require manual review.

We were linting against usages of `fdescribe` and `fit` by referencing the `no-jasmine-focus` rule which isn't installed, causing tslint to log the following:
```
Could not find implementations for the following rules specified in the configuration:
no-jasmine-focus
Try upgrading TSLint and/or ensuring that you have all necessary custom rules installed.
If TSLint was recently upgraded, you may have old rules configured which need to be cleaned
```
These changes switch to using the built-in `ban` rule.

This commit contains the basic runner logic and a couple of sample test cases
for the "full compile" compliance tests, where source files are compiled
to full definitions and checked against expectations.

Rather than running ng-dev via ts-node, going forward ng-dev is generated and run
locally via node. Additionally, the generated file is tested on each commit to
ensure that the local generated version stays up to date.

The legacy HTTP package was deprecated in v5 with the launch of
@angular/common/http. The legacy package hasn't been published
since v7, and will therefore not include a migration.

Switches our tslint setup to the standard `tslint.json` linter excludes.
The set of files that need to be linted is specified through a Yarn script.
For IDEs, open files are linted with the closest tslint configuration, if the
tslint IDE extension is set up, and the source file is not excluded.
We cannot use the language service plugin for tslint as we have multiple nested
tsconfig files, and we don't want to add the plugin to each tsconfig. We
could reduce that bloat by just extending from a top-level tsconfig that
defines the language service plugin, but unfortunately the tslint plugin does
not allow the use of tslint configs which are not part of the tsconfig project.
This is problematic since the tslint configuration is at the project root, and we
don't want to copy tslint configurations next to each tsconfig file.
Additionally, linting of `d.ts` files has been re-enabled. This has been
disabled in the past and a TODO has been left. This commit fixes the
lint issues and re-enables linting.

Since we build and publish the individual packages
using Bazel and `build.sh` has been removed, we can
safely remove the `rollup.config.js` files which are no
longer needed because the `ng_package` bazel rule
automatically handles the rollup settings and globals.

Now that we have --noImplicitAny we don't need these checks for explicit types in specific locations.
Also re-enable the check to disallow keywords as variable names.
