Add type-check and unify tsconfig (#10667)

This adds a new `pnpm type-check` that leverages `turbo` to validate the TypeScript code. This can be run at the top-level or for an individual package.

The `test-lint` workflow will run it after linting and doing the prettier check.

As apart of this effort, each package's `tsconfig.json` has been simplified. There's a new top-level `tsconfig.base.json` file that extends the Vercel Style Guide for TypeScript. Each package's `tsconfig.json` has been audited and previously suppressed rules that no longer apply have been removed. The result is each package's `tsconfig.json` is greatly simplified and we can control common settings in the base config while keeping the flexibility of package-level overrides.

Lastly, in `package/cli`, `pnpm build` calls `scripts/build.mjs` which calls `scripts/compile-templates.mjs`. The `compile-templates.mjs` file was generating invalid TypeScript code. I've fixed it and now it's happier than ever.

Note: In order to run `pnpm type-check`, you must first `pnpm build` because we need the `.d.ts` definition files.
