This lays the groundwork for making SparseBitSet serializable.
FontFamily.addFont is only used when the FontFamily is constructed.
Thus, instead of calling FontFamily.addFont multiple time, passes
Font list to the constructor. By this change, FontFamily can be
immutable now.
By making FontFamily immutable, We can create FontFamily with
pre-calculated SparseBitSet.

Change language score calculation in the calculation of the font family.
Instead of language and script matching, a match in subtag is added.
In addition, a match in subtag has a higher priority than a match in
script. The score levels are divided into 5 score levels and the limit
of the number of font languages is changed to 12 from 17. Multiple
languages selection rule could to be added in the future.

This is 2nd attempt of Ifcd7a348d7fb5af081192899dbcdfc7fb4eebbf9
After Id766ab16a8d342bf7322a90e076e801271d527d4, GetTable is no longer
used in production due to poor performance and it is now only used in
tests. This CL removes GetTable interface from MinikinFont and update
tests code to use new interfaces, GetFontData, GetFontSize and
GetFontIndex.

This is partial revert of Iced1349e3ca750821d8882c551551f65bb569794.
Due to sorting of target family vectors, the font family order from XML
settings file is broken. Making unique operation stable doesn't fix the
issue completely since some font families are appended for the fallback
which also breaks the original order.
By this change, itemization becomes 3x slower than before if variation
selector is appended.

Unicode recommends that the zwj sequences should be emoji presentation
even if they don't have the proper U+FE0F. Thus always lookup the glyph
for the code point before and after zwj as if they have a U+FE0F
variation selector.

FEMALE SIGN(U+2640), MALE SIGN(U+2642), StAFF OF AESCULAPIUS(U+2695)
will be used as the ZWJ sequenced in gender balanced emoji sequence.
To be in the same run with ZWJ, mark these emoji as sticky chracters.
With this fix, Female police officer sequence will be shown correctly
regardless of VS16.

This fixes following three memory leaks in test utilities.
There is no problem in production code and this CL doesn't affect
any production behaviors.
- SkTypeface leaks due to forget calling SkSafeUnref in dtor.
- MinikinFontForTest leaks during constructing FontCollection.
- FontCollection leaks due to unnecessary AddRef.

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.

To add perftests and reuse some utility classes, reconstruct
test directory structure.
- Move unit tests from minikin/tests to minikin/tests/unittests
- Extract utilitiy classes to minikin/tests/utils which will be
used by perftests eventually.
