Remove unused features from CodeFeatures
https://bugs.webkit.org/show_bug.cgi?id=78804

Reviewed by Gavin Barraclough.

* parser/Nodes.h:
* parser/ASTBuilder.h:
(JSC::ClosureFeature):
(JSC::ASTBuilder::createFunctionBody):
(JSC::ASTBuilder::usesClosures):
Remove "ClosureFeature".  Since we track captured variables more
precisely, this bit doesn't do us any good.

(JSC::AssignFeature):
(JSC::ASTBuilder::makeAssignNode):
(JSC::ASTBuilder::makePrefixNode):
(JSC::ASTBuilder::makePostfixNode):
(JSC::ASTBuilder::usesAssignment):
Similarly, remove AssignFeature.  It is unused.
