[DOC] Enhanced RDoc for String (#5685)

Treats:

    #chars
    #codepoints
    #each_char
    #each_codepoint
    #each_grapheme_cluster
    #grapheme_clusters

Also, corrects a passage in #unicode_normalize that mentioned module UnicodeNormalize, whose doc (:nodoc:, actually) says not to mention it.
