Subject: [ruby-core:89188] [Ruby trunk Feature#14802] Update Unicode data to Unicode Version 11.0.0

Issue #14802 has been updated by naruse (Yui NARUSE).


Just a note, the definition of extended grapheme cluster is changed in Unicode 11 (Unicode�� Standard Annex #29
UNICODE TEXT SEGMENTATION revision 33: https://www.unicode.org/reports/tr29/tr29-33.html)
This affects Regexp /\X/ which is hardcoded in node_extended_grapheme_cluster() in regparse.c.

```
( CRLF
| Prepend*
( RI-sequence | Hangul-Syllable | !Control )
( Grapheme_Extend | SpacingMark )*
| . )
```

```
crlf 
| Control 
| precore* core postcore*
```
