2aaae6fc70 LibJS: Avoid ToPropertyKey for spreading in PutByValue(WithThis)
This is not we're supposed to do according to https://tc39.es/ecma262/#sec-runtime-semantics-propertydefinitionevaluation
Furthermore, this was observable by ToPrimitive looking up toString and
valueOf and potentially calling them if they exist. The big ticket
issue however is that for objects without toString and valueOf, such as
null-proto objects, this would unexpectedly throw.

3ceedbd16a LibJS: Allow assignment expression in spreading property definition
See: https://tc39.es/ecma262/#sec-runtime-semantics-propertydefinitionevaluation
PropertyDefinition : ... AssignmentExpression
Also add a test for this in array spreading, which already had this in
place.

c114be95f5 LibJS: Use CopyDataProperties when spreading in object expressions
Before this was a mix of different strategies but copy_data_properties
does all of that in a spec way.
This fixes numeric properties in object spreading. And ensures that any
new properties added during spreading are not taken into account.
