RenderQuote has giant function for language to quotes map
https://bugs.webkit.org/show_bug.cgi?id=115807

Reviewed by Anders Carlsson.

Source/WebCore:

* rendering/RenderQuote.cpp:
(WebCore::RenderQuote::RenderQuote): Updated for m_isAttached name change.
(WebCore::RenderQuote::~RenderQuote): Updated for name change, and also split
assertion with && in it into two separate assertions.
(WebCore::checkNumberOfDistinctQuoteCharacters): Added. Helper function that is used
to check that the number of distinct quote characters is small enough to fit into
our fixed size array below.
(WebCore::quotesForLanguage): Replaces the old quotesDataLanguageMap function.
Returns a pointer to a struct that contains the four quote characters. This new
function doesn't have the massive amount of code that the old one did. We use the
standard library bsearch function to do a binary search.
(WebCore::stringForQuoteCharacter): Added. This returns a string for a given quote
character; one string for any given character.
(WebCore::quotationMarkString): Added. Returns the string for the quotation mark.
(WebCore::apostropheStringImpl): Added. Returns the string for the apostrophe.
(WebCore::RenderQuote::originalText): Rewrote this to include all the logic that
used to be in the quotesData function.
(WebCore::RenderQuote::attachQuote): Tweak assertions as above. Removed unneeded
special case for the first quote in a RenderView; sharing the code is better and
there is no significant performance difference. Also use m_isAttached directly
when looking at predecessores so there is no need for an isAttached function.
(WebCore::RenderQuote::detachQuote): Updated assertions and for name change.
(WebCore::RenderQuote::updateDepth): Ditto.

* rendering/RenderQuote.h: Removed unneeded includes. Marked the class FINAL since
we call the originalText function in the class and we don't want to do a virtual
function dispatch for that. Removed uneeded const from an argument. Removed a
stray semicolon. Removed the quotesData and isAttached functions, since they are no
longer needed. Renamed m_attached to m_isAttached.

* rendering/style/QuotesData.cpp: Removed the overload of QuotesData::create that
takes four quote strings. This was only used to build up the quotes table.
* rendering/style/QuotesData.h: Ditto.

Source/WTF:

* wtf/unicode/CharacterNames.h: Added a couple of character names.
