Add inherited flag to CSSProperties.in

This patch adds the flag 'inherited' to CSSProperties.in, replacing the
existing switch statement in CSSProperty.cpp. The primary use for
isInheritedProperty appears to be as part of the MatchedPropertiesCache
optimisation.

I've added the inherited flag to overflow-wrap and paint-order, which
are inherited in the code and specs[1][2] but were not returning true
in the switch. As far as I can tell, this has no difference aside from
making us still use the MatchedPropertiesCache if these are explicitly
set to inherit. I also added a fixme indicating that the property
resize shouldn't inherit by default.
