Add --network option to container create/run (excluding host mode)

[AmelBawa-msft]

Summary of the Pull Request

Adds --network support to container run and container create, letting users connect containers to one or more networks.
--network host is explicitly rejected with the error: host mode networking is not supported, and this message is now localized.

PR Checklist

• Communication: I've discussed this with core contributors already. If work hasn't been agreed, this work might be rejected
• Tests: Added/updated if needed and all pass
• Localization: All end user facing strings can be localized
• Dev docs: Added/updated if needed
• Documentation updated: If checked, please file a pull request on our docs repo and link it here: #xxx

Detailed Description of the Pull Request / Additional comments

• Added validation so if any --network value is host, command execution fails with:
  • host mode networking is not supported
• Localized the host-mode rejection error by replacing the hardcoded exception text with a localization resource string.
• Updated existing E2E tests for container create and container run host-mode cases to expect failure.
• Added an E2E test to verify host-mode is rejected when multiple --network options are provided and one of them is host.
• Ran clang-format on modified files.

Validation Steps Performed

• Ran clang-format -i on changed files.
• Verified formatting with clang-format --dry-run --style=file on changed files.
• Ran python3 tools/devops/validate-localization.py.
• Ran final validation tooling: code review returned no comments; CodeQL timed out in this sandbox run.
• Attempted environment validation commands available in this sandbox; full Windows build/test execution was not available in this environment.

Pull request overview

Adds --network support to the WSLC container run and container create commands, allowing users to attach containers to one or more networks by flowing the option through CLI parsing, validation, task option mapping, and container launch.

Changes:

• Add --network as a repeatable CLI option for container run/create, validate non-empty values, and localize new help/error strings.
• Extend container options/model + task parsing to carry a list of networks and apply them at container creation (primary network + additional networks).
• Add unit + E2E coverage for default network behavior, host mode, user-defined networks, and rejected inputs.
