chore: upgrade to prettier v2 + enforce import types (#21013)Co-authored-by: Satish Gandham <hello@satishgandham.com> Co-authored-by: Satish Gandham <satish.iitg@gmail.com>
## Description

This PR upgrades Prettier to v2 + enforces TypeScript’s [`import
type`](https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-8.html#type-only-imports-and-export)
syntax where applicable. It’s submitted as a separate PR so we can merge
it easily.

As a part of this PR, we reformat the codebase heavily:
- add `import type` everywhere where it’s required, and
- re-format the code to account for Prettier 2’s breaking changes:
https://prettier.io/blog/2020/03/21/2.0.0.html#breaking-changes

This PR is submitted against `release` to make sure all new code by team
members will adhere to new formatting standards, and we’ll have fewer
conflicts when merging `bundle-optimizations` into `release`. (I’ll
merge `release` back into `bundle-optimizations` once this PR is
merged.)

### Why is this needed?

This PR is needed because, for the Lodash optimization from
7cbb12af88,
we need to use `import type`. Otherwise, `babel-plugin-lodash` complains
that `LoDashStatic` is not a lodash function.

However, just using `import type` in the current codebase will give you
this:

That’s because Prettier 1 can’t parse `import type` at all. To parse it,
we need to upgrade to Prettier 2.

### Why enforce `import type`?

Apart from just enabling `import type` support, this PR enforces
specifying `import type` everywhere it’s needed. (Developers will get
immediate TypeScript and ESLint errors when they forget to do so.)

I’m doing this because I believe `import type` improves DX and makes
refactorings easier.

Let’s say you had a few imports like below. Can you tell which of these
imports will increase the bundle size? (Tip: it’s not all of them!)

```ts
// app/client/src/workers/Linting/utils.ts
import { Position } from "codemirror";
import { LintError as JSHintError, LintOptions } from "jshint";
import { get, isEmpty, isNumber, keys, last, set } from "lodash";
```

It’s pretty hard, right?

What about now?

```ts
// app/client/src/workers/Linting/utils.ts
import type { Position } from "codemirror";
import type { LintError as JSHintError, LintOptions } from "jshint";
import { get, isEmpty, isNumber, keys, last, set } from "lodash";
```

Now, it’s clear that only `lodash` will be bundled.

This helps developers to see which imports are problematic, but it
_also_ helps with refactorings. Now, if you want to see where
`codemirror` is bundled, you can just grep for `import \{.*\} from
"codemirror"` – and you won’t get any type-only imports.

This also helps (some) bundlers. Upon transpiling, TypeScript erases
type-only imports completely. In some environment (not ours), this makes
the bundle smaller, as the bundler doesn’t need to bundle type-only
imports anymore.

## Type of change

- Chore (housekeeping or task changes that don't impact user perception)


## How Has This Been Tested?

This was tested to not break the build.
