In the function onigenc_unicode_case_map() in enc/unicode.c, deal
with the case that the ONIGENC_CASE_IS_TITLECASE flag is set on
lowercase characters. This is in preparation for Georgian Mtavruli,
which are uppercase but not titlecase, in Unicode 11.0.0.

- enc/unicode/case-folding.rb:
- Convert unpredicted case to actual flag setting
- Eliminate an unused variable
- Change a variable name to avoid a warning

In ASCII, 'a' is bigger than 'A'. Which means 'A' - 'a' is a negative
number (-32, to be precise). In C, the type of 'a' and 'A' are signed
int (cf: ISO/IEC 9899:1990 section 6.1.3.4). So 'A' - 'a' is also a
signed int. It is `(signed int)-32`.
The problem is, OnigCodePoint is unsigned int. Adding a negative
number to a variable of OnigCodepoint (`code` here) introduces an
unintentional cast of `(unsigned)(signed)-32`, which is
4,294,967,264. Adding this value to code then overflows, and the
result eventually becomes normal codepoint.
The series of operations are not a serious problem but because
`code >= 'a'` holds, we can `(code - 'a') + 'A'` to reroute this.

- common.mk: Change Unicode version to 11.0.0
- enc/unicode/case-folding.rb, enc/unicode.c: Initial changes to deal with
Gregorian Mtavruli. This should bring us up to the same level as e.g.
Python 3.7, by following the Unicode tables exactly. But it will
produce undesirable (mixed-case) results for String#capitalize.
This will be addressed in a later commit.

let "tool/update-deps --fix" fill in the rest.
Hopefully this fixes problems with some CI builds
after r58359. Further changes to other ext/-test-/

* meta character \X matches Unicode 9.0.0 characters with some workarounds
for UTR #51 Unicode Emoji, Version 4.0 emoji zwj sequences.
[Feature #12831] [ruby-core:77586]
The term "character" can have many meanings bytes, codepoints, combined
characters, and so on. "grapheme cluster" is highest one of such words,
which means user-perceived characters.
Unicode Standard Annex #29 UNICODE TEXT SEGMENTATION specifies how to
handle grapheme clusters (extended grapheme cluster).
But some specs aren't updated to current situation because Unicode Emoji
is rapidly extended without well definition.
It breaks the precondition of UTR#29 "Grapheme cluster boundaries can be
easily tested by looking at immediately adjacent characters". (the
sentence will be removed in the next version)
Though some of its detail are described in Unicode Technical Report #51
UNICODE EMOJI but it is not merged into UTR#29 yet.
