This creates an exact map of the emoji font and adds the following
tests:
* Test that all 'emoji style' variation sequences exist in the color
emoji font.
* Test that the emoji font contains the exact same character set that
we expect.
* Test that all unsupported flags map to the same flag tofu glyph.
* Test that the reverse of ZWJ sequences exist in the font and map to
the same glyph.
* Test that legacy PUA Android emoji are supported.
* Test that all emoji sequences that should map to the same glyph do
so, but no other sequences map to the same glyph.

This re-enables the emoji font tests, but doesn't run the tests if
SMALLER_FONT_FOOTPRINT is set.
Additionally, we test that there's one and only one emoji font in the
fallback chain.

Hyphenation patterns are being added for 22 languages and they need
entries in LANG_TO_SCRIPT
This CL is a prerequisite to the following CL to add hyphenation
patterns for more languages:

On builds where SMALLER_FONT_FOOTPRINT environment variable is set, some
of the fonts are not included in the build which causes emoji checks to
fail. This CL temporarily disables emoji checks.

1. Check that dual-use text/emoji character that default to text
style are available in a font before the emoji font. (Exceptions are
Unicode 7.0 characters that Noto Symbols doesn't support yet and four
odd characters that should be added to the Noto Symbols subset.)
2. Remove previous workaround for default emoji-style characters that
were in the Noto CJK fonts, since they are now subsetted out from
Noto CJK.

1. Check that all emoji characters are supported in emoji fonts.
2. Check that no default-emoji characters are included in any font
that can get a higher score then the color emoji font, either by
being before it or by having a language/script assigned.

Various tests have been added:
1. Availability of hyphens: Make sure that every font used for
rendering a language that is automatically hyphenated includes either
of Unicode hyphen characters U+2010 HYPHEN or U+002D HYPHEN-MINUS.
2. Range of values: Make sure that styles, weights, and styles belong
to certain limited sets.
