Fixes https://github.com/facebook/react/issues/26911,
https://github.com/facebook/react/issues/26860.
Currently, we are parsing user agent string to determine which browser
is running the extension. This doesn't work well with custom user
agents, and sometimes when user turns on mobile dev mode in Firefox, we
stop resolving that this is a Firefox browser, extension starts to use
Chrome API's and fails to inject.
Changes:
Since we are building different extensions for all supported browsers
(Chrome, Firefox, Edge), we predefine env variables for browser
resolution, which are populated in a build step.
In the extension, currently we do the following:
1. check whether there's at least one React renderer on the page
2. if yes, load the backend to the page
3. initialize the backend
To support multiple versions of backends, we are changing it to:
1. check the versions of React renders on the page
2. load corresponding React DevTools backends that are shipped with the
extension; if they are not contained (usually prod builds of
prereleases), show a UI to allow users to load them from UI
3. initialize each of the backends
To enable this workflow, a backend will ignore React renderers that does
not match its version
This PR adds a new file "backendManager" in the extension for this
purpose.

I've tested it on Chrome, Edge and Firefox extensions
## Summary
resolves#24522
To upgrade to Manifest V3, one of the biggest issue is that we are no
longer allowed to add a script element with code in textContent so that
it would run synchronously. It's necessary for us because we need to
inject a global hook for react reconciler to detect whether devtools
exist.
To do that, we'll leverage a new API
`chrome.scripting.registerContentScripts` in V3. Particularly, we rely
on the "world" option (added in Chrome v102
[commit](e5ad3451c1))
to run it in the "main world" on the page.
This PR also renames a few content script files so that it's easier to
tell them apart from other extension scripts and understand the purpose
of each of them.
Manifest V3 is not yet ready for Firefox, so we need to keep some code
for compatibility.
## How did you test this change?
`yarn build:chrome && yarn test:chrome`
`yarn build:edge && yarn test:edge`
`yarn build:firefox && yarn test:firefox`
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.
* Added rudimentary context menu hook and menu UI
* Added backend support for copying a value at a specific path for the inspected element
* Added backend support for storing a value (at a specified path) as a global variable
* Added special casing to enable copying undefined/unserializable values to the clipboard
* Added copy and store-as-global context menu options to selected element props panel
* Store global variables separately, with auto-incremented name (like browsers do)
* Added tests for new copy and store-as-global backend functions
* Fixed some ownerDocument/contentWindow edge cases
* Refactored context menu to support dynamic options
Used this mechanism to add a conditional menu option for inspecting the current value (if it's a function)
* Renamed "safeSerialize" to "serializeToString" and added inline comment
