Use search and search_api_autocomplete form elements for search form and implement auto-submit

I have created a MR to change the input type, please have a look 😇

I just realized that search_api_autocomplete provides it's own form element that we could use here and that would allow us to support auto-submit.

In order to get a search insteaf of a text field you would need to apply the patch from ✨ Use search form element instead of text Needs review .

I think there is no need to have "Auto Submit" configuration setting on Endpoint entity, because this setting exists on Search API Autocomplete entity. If anyway the form element from that module is used, auto-submit setting from it could be used as well. Endpoint entity has method getAutocomplete that returns the autocomplete object in response, if it exists. It can be used to get the auto-submit setting from Search API Autocomplete.

The looks good and works, maybe then the search api decoupled autocomplete endpoint is also not needed at all, because it is doing the same as search_api_autocomplete anyway, as here the search api autocomplete endpoint is used.

Maybe then the access control for standard search_api_autocomplete should be extended if it was created from endpoint.

Related issue was created for removing custom search_api_decoupled_autocomplete route as follow up to this. Merging this MR.
