mruby.h: rename ASCII flag to SINGLE_BYTE
...
This flag means all the characters in the string can be represented by a
single byte, i.e., the string does not contain any multi-byte character.
Those characters are likely ASCII characters, but may be a part of broken
UTF-8 sequence, so the term 'ASCII' is not sufficient.

string.c (str_index_str_by_char): simplify using str_index_str()
...
Instead of its own version of quick search, now we use str_index_str()
and adjust character position. This change makes searching 4 times
faster in some cases; ref #6143

If (ch < 0x80) the length of the character (in bytes) should be 1, so we
don't have to call mrb_utf8len().
