Integrations setup (#4354)
* add integration test tools

* setup jest in the integrations folder

* add `test:integrations` script

The default `npm test` script will ignore all the tests in the
`integrations` folder.

* add integration tests with `webpack 5`

* add integration tests with `postcss-cli`

* add `npm run install:integrations` script

This script will run `npm install` in every integration, and in the
integrations folder itself (to setup Jest for example).

* add `toIncludeCss` custom matcher

* increate Jest timeout for integration tests

* add integration tests with `vite`

* add integration tests with `webpack 4`

* add isomorphic fetch

* add the ability to wait for specific stdout/stderr output

* write vite tests, assert using API calls

We will wait for the correct stdout/stderr output, once we know that we
can request the fresh css, we will fetch it and make assertions
accordingly.

Port is currently hardcoded, maybe we should use a packaage to ensure
that we use a free port.

* add integration tests with `rollup`

* add integration tests with `parcel`

* run all integration tests in band

* add .gitignore in integrations folder
