Fix <AutocompleteArrayInput> silently ignoring emptyText and emptyValue

[erwanMarmelab]

Closes #8425

Problem

• <AutocompleteArrayInput> accepts emptyText and emptyValue but silently ignores them (as reported in The documentation says that <AutocompleteArrayInput> supports the emptyText property, but it does not work. #8425).
• emptyValue is still documented even though it is as much a no-op as emptyText (which was removed from the docs in [Doc] Remove emptyText prop from <AutoCompleteArrayInput> doc as it is not supported #9073).

Solution

• Remove the emptyValue prop from the <AutocompleteArrayInput> documentation.
• Log a development warning when either prop is passed to a multiple autocomplete input, instead of ignoring it silently.
