Customizable min suffix/prefix length for hyphenation in Minikin
With this change, different languages can have a different minimum
length for suffix and prefixes when hyphenating. Previously, the
defaults used for English, 2 and 3, were used for every language.
Bug: 35712376
Test: Minikin unit tests were updated and the pass

Correct hyphenation for various complex cases
This adds better support for Arabic script languages, Armenian,
Catalan, Hebrew, Kannada, Malayalam, Polish, Tamil, and Telugu by
adding various hyphenation types and edits appropriate for the
locales.
For Arabic script languages, soft hyphens act transparently with
regard to joining: If a line is broken at a soft hyphen where the two
characters around the soft hyphen were joining each other before,
they will continue to appear joining if the line is broken at the
soft hyphen and a hyphen glyph is inserted. This is needed for
Central Asian languages such as Uighur.
For Armenian, U+058A ARMENIAN HYPHEN is used for line breaks caused
by either automatic hyphenation or soft hyphens.
For Catalan, nonstandard line breaks are implemented for "l·l", which
hyphenates as "l-/l".
For Polish, when there is a line break at a hyphen, the hyphen is
repeated at the next line.
For the South Indic languages, when breaks happen due to soft breaks
or automatic hyphenation, no visible hyphen is inserted, although a
penalty is added.
For Hebrew, support for using U+05BE HEBREW PUNCTUATION MAQAF has
been implemented, but it's turned off pending confirmation of
desirability.
Also, hard hyphens, which previously had no penalty added for
breaking the line after them, now have the same penalty as an
automatic or soft break, with the difference that no hyphen is
inserted when they break.
Finally, some bugs have been fixed with hyphenating multiscript and
multi-font words.

Always use minikin namespace.
Here is a new policy of the namespace of minikin.
- All components should be in minikin namespace.
- All tests are also in minikin namespace and no anonymous namespace.

Binary format for hyphenation patterns
In the current state, hyphenation in all languages than Sanskrit seems
to work (case-folding edge cases). Thus, we just disable Sanskrit.
Packed tries are implemented, but not the finite state machine
(space/speed tradeoff).
This commit contains a throw-away test app, which runs on the host.
I think I want to replace it with unit tests, but I'm including it in
the CL because it's useful during development.

Use ICU to lowercase words to hyphenate.
Previously, the standard C tolower() function was used, which
didn't support any characters beyond the basic ASCII letters.

Add hyphenation to line breaking
This patch adds hyphenation using the Liang hyphenation algorithm,
similar to TeX. It also improves the optimized line breaker so that
it works correctly and efficiently even when the line width is not
constant (there is a specialization for constant width, which is
probably worthwhile, but performance TODOs remain).
Still to be done:
* hyphenator has many shortcuts, only tested with English
* interaction between punctuation and hyphenation is problematic
