Addresses https://github.com/facebook/react/issues/32244.
### Chromium
We will use
[chrome.permissions](https://developer.chrome.com/docs/extensions/reference/api/permissions)
for checking / requesting `clipboardWrite` permission before copying
something to the clipboard.
### Firefox
We will keep `clipboardWrite` as a required permission, because there is
no reliable and working API for requesting optional permissions for
extensions that are extending browser DevTools:
- `chrome.permissions` is unavailable for devtools pages -
https://bugzilla.mozilla.org/show_bug.cgi?id=1796933
- You can't call `chrome.permissions.request` from background, because
this instruction has to be executed inside user-event callback,
basically only initiated by user.
I don't really want to come up with solutions like opening a new tab
with a button that user has to click.
Adding `__IS_NATIVE__` global, which will be used for forking backend
implementation. Will only be set to `true` for `react-devtools-core`
package, which is used by `react-native`.
Ideally, we should name it `react-devtools-native`, and keep
`react-devtools-core` as host-agnostic.
With this change, the next release of `react-devtools-core` should
append component stack as Error object, not as string, and should add
`(<anonymous>)` suffix to component stack frames.

The first log doesn't get a stack because it's logged before DevTools
boots up and connects which is unfortunate.
The second log already has a stack printed by React (this is on stable)
it gets replaced by our object now.
The third and following logs don't have a stack and get one appended.
I only turn the stack into an error object if it matches what we would
emit from DevTools anyway. Otherwise we assume it's not React. Since I
had to change the format slightly to make this work, I first normalize
the stack slightly before doing a comparison since it won't be 1:1.
Hermes parser is the preferred parser for Flow code going forward. We
need to upgrade to this parser to support new Flow syntax like function
`this` context type annotations or `ObjectType['prop']` syntax.
Unfortunately, there's quite a few upgrades here to make it work somehow
(dependencies between the changes)
- ~Upgrade `eslint` to `8.*`~ reverted this as the React eslint plugin
tests depend on the older version and there's a [yarn
bug](https://github.com/yarnpkg/yarn/issues/6285) that prevents
`devDependencies` and `peerDependencies` to different versions.
- Remove `eslint-config-fbjs` preset dependency and inline the rules,
imho this makes it a lot clearer what the rules are.
- Remove the turned off `jsx-a11y/*` rules and it's dependency instead
of inlining those from the `fbjs` config.
- Update parser and dependency from `babel-eslint` to `hermes-eslint`.
- `ft-flow/no-unused-expressions` rule replaces `no-unused-expressions`
which now allows standalone type asserts, e.g. `(foo: number);`
- Bunch of globals added to the eslint config
- Disabled `no-redeclare`, seems like the eslint upgrade started making
this more precise and warn against re-defined globals like
`__EXPERIMENTAL__` (in rollup scripts) or `fetch` (when importing fetch
from node-fetch).
- Minor lint fixes like duplicate keys in objects.

React currently suppress console logs in StrictMode during double rendering. However, this causes a lot of confusion. This PR moves the console suppression logic from React into React Devtools. Now by default, we no longer suppress console logs. Instead, we gray out the logs in console during double render. We also add a setting in React Devtools to allow developers to hide console logs during double render if they choose.
Also resolve an uncaught error in extension build (#18843).

DevTools previously used the NPM events package for dispatching events. This package has an unfortunate flaw though- if a listener throws during event dispatch, no subsequent listeners are called. I've replaced that event dispatcher with my own implementation that ensures all listeners are called before it re-throws an error.
This commit replaces that event emitter with a custom implementation that calls all listeners before re-throwing an error.
