Force enable V0 APIs for ZipArchiver extension.

This patch is a preparation for Shadow DOM V0, Custom Element V0 (CEv0) and HTML Imports removal.
Intent to Deprecate and Remove:
Though we soon make these APIs only available for test by turning the json5 feature flag
from status: "stable" to status: "test", there is browser tests/chrome internal components
that use them.

ZipArchiver is a one of them and this patch reenable the APIs for it.
We should migration it using new APIs.

TEST: browser_tests --gtest_filter=*FilesAppBrowserTest*zipFile* on patch
