* Update digitGroupingPattern to match CLDR 31: New versions of CLDR has
digit grouping pattern with decimal part. Update digitGroupingPattern
values in Message classes with this improved pattern.
Refer: http://unicode.org/reports/tr35/tr35-numbers.html
* Refer the following chart for the decimal patterns.
http://www.unicode.org/cldr/charts/31/by_type/numbers.number_formatting_patterns.html
* Uses PHP NumberFormatter class for the commafy implementation, which
is available in PHP 7.
* Some tests need to update to match the TR 35 spec
* The formatNum public method in Language.php is the preferred way to
use this feature. It does separator transformation and digit transformation
wherever applicable.
* Renamed the second param name for formatNum from noCommafy to noSeparators
* commafy method is deprecated and formatNum is preferred. Practically,
we are not just adding comma, but seperators according to the language.
Replaced some tests based on commafy methods with tests based on formatNum.
Note: The corresponding js implementation is not changed in this commit.
It would probably be a good idea to use globalize.js, which is also based
on the CLDR patterns.
Note: This patch preserves the existing off-by-one error in
$minimumGroupingDigits; T262500 will eventually fix this.

In some languages it's conventional not to insert a thousands
separator in numbers that are four digits long (1000-9999).
Rather than copy-paste the custom code to do this between 13 files,
introduce another option and have the base Language class handle it.
This also fixes an issue in several languages where this logic
previously would not work for negative or fractional numbers.
To implement this, a new option is added to MessagesXx.php files,
`$minimumGroupingDigits = 2;`, with the meaning as defined in
<http://unicode.org/reports/tr35/tr35-numbers.html>. It is a little
roundabout, but it could allow us to migrate the number formatting
(currently all custom code) to some generic library easily.

According to the typographical convention, a thousands separator
should not be inserted in numbers that are four digits long (between
1000 and 9999), unlike in English where it's usually acceptable.
This logic is currently implemented in LanguagePl::commafy().
