fix(ivy): keep i18n-annotated attributes in element attribute list (#29856) 

Prior to this change, element attributes annotated with i18n- prefix were removed from element attribute list and processed separately by i18n-specific logic. This behavior is causing issues with directive matching, since attributes are not present in the list of attrs for matching purposes. This commit updates i18n logic to retain attributes in the main attribute list, thus allowing directive matching logic to work correctly.
