chore[DevTools]: make clipboardWrite optional for chromium (#32262)

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.
