feat: Release renderOption for all systems

[gethinwebster]

Description

Remove @awsuiSystem core annotation from renderOption on select, autosuggest, and multiselect components, making custom option rendering available to all systems (including console).

This follows the same approach as button-dropdown renderItem (PR #4453). The component retains full control of accessibility (ARIA roles, keyboard navigation) regardless of custom rendering.

How has this been tested?

• TypeScript compilation passes with no new errors
• Documenter snapshots updated
• Existing unit and integration tests unaffected (annotation removal only)

Review checklist

Correctness

• Changes are backward-compatible — only removes a system gate, no API changes.
• No new browser features used.
• No accessibility impact — components retain full ARIA/keyboard management regardless of custom rendering.

Security

• No URL handling changes.

Testing

• Existing tests cover renderOption functionality (already tested in core system).
