[expo-notifications] Device push token fetching module (#6577)

# Why

To eventually deprecate ExpoKit.

# How

- created a new unimodule, disabling autolinking in the root projects
- implemented `getDevicePushTokenAsync` method in TS, then in native (on iOS we rely on system framework, on Android we're using Firebase Cloud Messaging)
- implemented listening to token changes

### Notable changes to TS implementation

- I had to juggle around types a bit to achieve what I wanted — for TS to discriminate by `type: keyof Platform.OS` value what is the type of `data` field and at the same time to use `data: any` for unsupported platforms. Types are ready, but I needed to use [`@ts-ignore`](0bd4687#diff-66b6995155cd1e190f53b012f5c2a857R43-R44) to get away with it.

### Notable changes to native implementation

- we use singleton module for listening to token changes [android](69ee9ef#diff-5f9ef5ef7358f7a9c8cc386d42ee934f), [ios](0aa2b66#diff-f8332f28b28ad9a24e0af0cb435876c7)
- on Android there's a service subclassing `FirebaseMessagingService` to which the singleton above subscribes [link](69ee9ef#diff-b6817886a179022070e2417712503fa9)

### Notable changes to web implementation

- eventually, I guess, developers would want to customize how their app responds to notifications — for this I added a `serviceWorkerPath` manifest field [commit](82e54ae)

# Test Plan

- tests in `test-suite` are passing on **all three platforms** (on web puppeteer has to be run in head…ful (?) mode, otherwise overriding permissions doesn't work, which is a [known issue](puppeteer/puppeteer#3279))
- push notifications sent to device push tokens are received on **all three platforms**
