fix(Select): ensure Select properly truncates long strings

Closes #14343

Adds in styles to truncate long Select strings. It also adds some logic to automatically generate a title attribute, which matches the behavior for Dropdown, Combobox, and other Listbox elements.

Changelog

New

• Styles to add ellipsis when text is too long
• Populate the title field with the currently selected item

Changed

• Changed the storybook SelectedItem values to more human-readable values.
• Added a long string to test truncation

Removed

• {{removed thing}}
