Paul Gschwendtner 5615928df9 build: no longer run tslint from within gulp task (#35800)
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.
