Summary:
This diff adds defaults to Jest.fn's type params.
An upcoming change to flow will be more restrictive about how we implicitly instantiation type arguments. Since the argument to jest.fn is often omitted, this signature is the single biggest offender of our new rules. To reduce the error diff, I'm adding reasonable defaults so that the mocked function can still behave like a function without adding extra flow errors where there were none before.

Summary:
Jest 27 [flips defaults](https://jestjs.io/blog/2021/05/25/jest-27#flipping-defaults), making "modern" fake timers (ie, `sinonjs/fake-timers`) the default, over "legacy", which we currently use.
We're not quite ready for modern timers yet, partly due to Promise polyfills (https://github.com/facebook/react-native/pull/34659), and also some internal issues with specific tests.
This makes our use of legacy timers explicit in preparation for an update to Jest. A switch to modern timers may follow later.

Summary:
Deprecates the nonstandard `Promise.prototype.done` method. This also removes one call site within React Native itself that relied on this method.
As part of this we are also removing React Native's custom Flow definition for `Promise` in favour of the standard one built into Flow. This will flag uses of `done` as type errors for anyone using the default app template's `.flowconfig`.
In a future release of React Native, we will remove the `done` method from the built-in `Promise` polyfill.
Changelog:
[General][Deprecated] - Deprecate the Promise.prototype.done method and log a warning when it's called in development.

This diff add types to some of the common globals so uses of
them through `global` are now typed.
All the globals are marked as read-only for their intented uses.
However, some of them do have write cites (mostly are in tests to
deliberately set up a special test environment). Those write cites
are considered as "necessary evil" and annotated as `FlowFixMe`.

Summary:
Generating this diff was difficult. We _will_ fix the issues with jscodeshift, but i don't want to block the syntax change on that.
To get this diff, I first codemodded all of xplat to use exact-by-default. Then i turned on implicit-inexact-object:error enforcement to get a list of errors showing places that violated the lint. With that, I used this to generate a list of `sed` commands to add `...`:
```
flow --json | jq '.errors | .[] | .message | .[] | .loc | {source, "line": .end."line", "column": .end."column"} | "\(.column),\(.line),\(.source)"' | sort -n -r | sed 's/"//g' | while read -r line; do echo $line; awk -F',' "{ print \"sed -i '\"\$2\"s/./...&/\"\$1\"' \" \$3 }"; done
```
Then I ran prettier, reverted generated files, and manually fixed up suppressions that got messed up.

Summary:
In Flow v0.99 we are changing function type annotations to be strict about their
static properties. This causes a small issue with the union of a Subcription and
`() => mixed` function type, where the latter is now understood to possibly have
an `unsubscribe` property with a mixed type.
This causes the following refinement check, which appears lower in this file, to
cause an error in the next version of Flow:
```
if (cleanup) {
if (cleanup.unsubscribe) {
cleanup.unsubscribe(); // <-- error here
}
// ...
}
```
In Flow v0.99, because `() => mixed` statics are now checked, Flow sees that
`cleanup.unsubscribe` might be `mixed`, which passes the conditional but could
cause an exception when called.
I also needed to change JestMockFn to have exact statics, because tests
sometimes use a value with that type in place of the cleanup function. That runs
into the `{} <: {+p?: void}` rule, which is an error. `{||} <: {+p?:void}` is
not an error.

Switches to the `nullthrows` package instead of using `fbjs/lib/nullthrows`.
The version of `nullthrows` in `fbjs` is outdated and already missing features that exist in the standalone `nullthrows` package.
Also, this mitigates the inevitable collision between `nullthrows` (as a Haste module) and `nullthrows` (as a `node_modules` dependency).
