LibJS/Bytecode: Always make own properties in object expressions

Browse source 
When building an object from an object expression, we don't want to
go through the full property setting machinery. This patch adds a new
PropertyKind::DirectKeyValue for PutById which guarantees that the
property becomes an own property.

This fixes an issue where setting the "__proto__" property in object
expressions wasn't working right.
