Add an explicit --data <data-URL> command-line option while keeping ordinary external top-level data: URLs blocked. The option preserves external-load semantics and opts in using LOAD_FLAGS_FORCE_ALLOW_DATA_URI. Tests cover startup and remote invocation, invalid input, external blocking, and null-principal behavior. Differential Revision: https://phabricator.services.mozilla.com/D322525
