Convert CFX_CSSPropertyTable to CFX_CSSData

This converts the existing class naming and references. The ::Entry
struct is converted to ::Property. The GetBy* methods are renamed to
GetPropertyBy*.

Free functions from other parts of the CSS code base are merged into
the class. GetCSSPropertyValueByName becomes ::GetPropertyValueByName
with a return value of ::PropertyValue*. GetCSSLengthUnitByName
becomes ::GetLengthUnitByName with a return value of
::LengthUnit*. GetCSSColorByName becomes ::GetColorByName with a
return value of ::Color*.
