In combination with the TS `noImplicitOverride` compatibility changes,
we also want to follow the best-practice of adding `override` to
members which are implemented as part of abstract classes. This
commit fixes all instances which will be flagged as part of the
custom `no-implicit-override-abstract` TSLint rule.
PR Close#42512
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.

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.
We've had issues such as the one I documented: https://github.com/Microsoft/TypeScript/issues/5187
This tslint check prevents this happening again.
This change also updates to the newest tslint which gets typings from npm.
