[Extensions] Handle extension acknowledgment of MV2 disabled stage

Chrome has announced that MV2 extensions will gradually no longer be
supported in the browser. None of these changes will take effect on any
Chrome channel before June, 2024. See more information at
https://developer.chrome.com/blog/resuming-the-transition-to-mv3.

The second stage of the deprecation will disable unsupported MV2 extensions and has user-visible notices in chrome://extensions.

This CL connects the 'keep for now' button in the extension's action
menu to acknowledge the notice for the rest of the stage. This means
when the button is clicked:
  - extension is removed from mv2 deprecation panel in
    chrome://extensions
  - mv2 deprecation message in chrome://extensions detail page is
    hidden for the rest of the stage.

For this we:
  - Notify ManifestV2ExperimentManager to update the "extension
    acknowledged in disabled stage" via
    developerPrivate.updateExtensionConfiguration
  - Listen for "extension acknowledged in disabled stage" pref changes
    via extension info updates

Screencast: https://drive.google.com/file/d/1aE0DL8oDD7rDYTdMsjuFFC5FWwWh4PMc/view?usp=drive_link
First, we open a browser in exp stage 1 (warning) and dismiss the
notice. Then, we open a browser in exp stage 2 (disabled), which has
the notice again, and dismiss the notice.
