feat(ui-component): Code list validation

[TomasEng]

Description

Added validation for duplicate values on the code list editor. When there are duplidated values,

• the onChange event is not triggered,
• the individual input fields containing duplicated values reach native invalid state, with an error message being shown on focus (using the native reportValidity method), and
• a general error message is diplayed at the bottom.

Related Issue(s)

• Implement new StudioCodelistEditor component #13342

Verification

• Your code builds clean without any errors or warnings
• Manual testing done (required)
• Relevant automated test added (if you find this hard, leave it and we'll help out)
