strv: convert strv_split_quotes into a generic strv_split_extract
strv_split_extract is to strv_split_quotes as extract_first_word was to unquote_first_word. Now there's extract_first_word for extracting a single argument, extract_many_words for extracting a bounded number of arguments, and strv_split_extract for extracting an arbitrary number of arguments.
