Refactor MessageTimestamp using MVVM and move to shared-components (#31988)

* Create a MessageTimestampView in shared components * Switching to use shared component and view model in element-web * Add .mx_MessageTimestamp tp _common.pcss since it is used extensively in element-web * Added comments to view model * Updating after Add options for consistent screenshots * Moved rendering of late icon to EventTile * Update shared component snaps * Added I18nContext.Provider to Modal.tsx and HtmlExport.tsx to make them work with shared components * Avoid circular dependencies for ModuleApi * Adjust role and wire handlers in view model * Change to role="link" * Revert I18nContext.Provider changes * Updated snapshot * Provide I18nContext for shared-components used inside dialogs and html-export rendered in a separate root. * Add patch for react-sdk-module-api to shared components * Add setProps to MessageTimeViewModel and useEffect on wrappers * Added more tests to improve coverage * Changes after PR review * Use specific setters in the viewmodel more relating to the business logic. * Remove unused CSS properties * New snapshot after merge * Removed aria-hidden logic and display tooltips in stories * Remove await for toolitp in HasInhibitTooltip story * Add screenshots with visible tooltips * Fixes after merge and review comments * Updated snapshots for unit tests * Removed one test since tooltips are not rendered to snapshots
