[Extensions] Introduce a ScopedExtensionDialogAutoConfirm

Introduce a ScopedExtensionDialogAutoConfirm to use in place of the
ExtensionUninstallDialog::ScopedAutoConfirm and the unscoped
ExtensionInstallPrompt::g_auto_confirm_for_testing. Also use this in the
management api instead of it's g_auto_confirm_for_testing.

TBRs for small mechanical changes.
