Split CSSPrimitiveValue into CSSPrimitiveValue and CSSIdentifierValue
Split CSSPrimitiveValue into two subtypes, CSSPrimitiveValue (for
numerical and calc values) and CSSIdentifierValue (for identifiers).
This is part of a larger effort to split up CSSPrimitiveValue.
This patch is meant to be entirely mechanical changes; if it passes all
tests with no behaviour changes, it has been implemented correctly. The
patch itself was mainly done with find-and-replaces to createKeyword()
and convertTo<>(), then fixing any other errors, sucha as those
resulting from irregular flow (e.g. if (!x.isPrimitiveValue) return;
in CSSToStyleMap) or similar.
The largest change has been to CSSPrimitiveValueMappings.h, since the
convertTo<> method has been moved to CSSIdentifierValue. Also, a
create(Length, zoom) method was added to CSSValue temporarily, and
callers will later change to switch between which create method
(CSSPrimitiveValue or CSSIdentifierValue) they wish to use.
