Add CSS hyphens property behind the test flag

This patch adds the CSS hyphens property behind the test flag.

This property was once added then removed in  crbug.com/47083 . The
member field in StyleRareInheritedData was not removed and and thus
changes to StyleRareInheritedData and ComputedStyle::diffNeeds* are
already in place.

Enable hyphens: auto and none in BreakingContext

This patch enables "hyphens: auto"[1] (automatic hyphenation using the
dictionaries) and "hyphens: no" (disables soft-hyphens for heading and
a11y) in BreakingContext, along with a mock hyphenation dictionary for
testing.

The code to support hyphenation in InlineTextBox, LayoutText,
LayoutTreeAsText, etc. were still there and reused in this code.

LayoutText::computePreferredLogicalWidths() needs to support the
"hyphens" property to compute the min-content width[2]. This will be in
following patches.

Platform support for dictionaries will also be in following patches.

Detailed control of hyphenation defined in CSS Text Level 4[3] is not
included in this phase.

Compute correct min-content width when hyphenation is enabled

This patch computes the correct min-content width[1] when hyphenation
makes it shorter.

The basic logic is as same as the one removed in [2], but:
1. Updated to the current code base.
2. Shape with context, the same way as BreakingContext in [3].
3. Drop support for CSS Text Level 4 properties.

Unlike the line breaker which needs to find one hyphen location,
computing min-content needs to find all hyphen locations. A method to
get all hyphen locations in a word is added for platforms that can get
all hyphen locations at once.

Add Minikin Hyphenation engine for Android

This patch adds the Minikin Hyphenation engine for Android. Dictionary
files loaded by [1] are passed to Minikin in this CL and used to
determine the hyphenation locations.

Two files are adopted from Minikin in Android Open Source Project[2],
in the similar way as we adopted MPL code[3].

With this patch, Android supports hyphenation behind the experimental
flag, following Mac[4].

Linux and Windows don't have built-in dictionaries. Supporting these
platforms will be later.

Fix hyphenation for lang="de" and other fallback on Android

This patch fixes 3 issues for hyphenation to work on Android for
lang="de" and some other languages.

1. Android requires additional fallback mapping for "de" and some other
   languages.
2. ASCII digits must be a valid locale.
3. When fallback occurs from platformGetHyphenation(), HashMap fails
   to store the loaded dictionary when it calls get() recursively.

Also fallback list was changed to be lower case to avoid run-time
conversions.

Add UMA to measure time to open hyphenation dictionary

This patch adds UMA to measure time to open hyphenation dictionary.

The previous CL[1] added UMA that includes IPC as "Hyphenation.Open",
but this metric measures the time of the file task without the IPC.

Split the automatic hyphenation for Win/Linux/ChromeOS to issue 652964.

Please provide the following information, so that chrome test engineering team can proceed with testing.

1. Is the feature code complete & enabled in the trunk and ready for testing?
2. Does this require manual testing?
3. Any specific setup / flags required?
4. Do we have enough UMA coverage to measure the stability? Its highly recommend always adding Stability.Counts and CrashExitCodes.* to your json to measure stability of your experiment.

1. Is the feature code complete & enabled in the trunk and ready for testing?

Yes.

2. Does this require manual testing?

No, there's no user interactions. When the page has "hyphens" property, hyphenations should be enabled/disabled, and all existing features should work as they were.

3. Any specific setup / flags required?

For automatic hyphenations:
a. Mac or Android M MR1+ only.
b. The page has "hyphens: auto" in its CSS.
c. The language of the page is supported.
   - The language of the page is from the "lang" attribute (e.g., <html lang=en>) or from the system language.
   - Supported language varies by OS versions.
Confirm the page is hyphenated, and existing features work as they were.

For disabling soft hyphens:
a. The page has "hyphens: none" in its CSS.
b. The page has "&shy;" in its HTML.
Confirm the page does not hyphenate at "&shy;".

4. Do we have enough UMA coverage to measure the stability? Its highly recommend always adding Stability.Counts and CrashExitCodes.* to your json to measure stability of your experiment.

Sorry, I don't understand this, any pointers to learn what they are?

Approving from Desktop Team since there is no requirement for manual testing. Requesting Christine to flip the bit after checking in Android.

Thanks, rsgavara@ is looking at this for Android testing.

Approving from Chrome on Android team as well since there is no manual testing required as per #25. We checked browsing website given in  issue 668684  just to make sure that there are no crashes. Flipping Test bit to Yes since Desktop also approved

Any pregress on windows?
Is there a new issue for that?

#30: thank you for your comments:
> Any pregress on windows?
> Is there a new issue for that?

Issue 652964 is the one, appreciate if you could star it.

Unfortunately, we're not making good progress on how to download dictionaries yet.

I hoped Windows to make the API for the hyphenation engine they use for WPF public in the Anniversary Update, but that didn't happen. I keep asking to MS but haven't got good response yet.
