[Extensions] Use policy-enforced update URL in app uninstall dialog

This change gives ExtensionManagement control over update URL used when
updating extensions. Previously only first install was affected, all
later updates used update URL from the extension manifest. Now update
URL from the policy can be used if extension management said so.
This change is split into multiple CLs.

Update URL from policy is handled in
https://chromium-review.googlesource.com/c/chromium/src/+/2593260.
