LibJS+LibWeb: Prevent double invocation of [[GetOwnProperty]]

Browse source 
The `[[GetOwnProperty]]` internal method invocation in
`OrdinarySetWithOwnDescriptor` was being invocated again with the same
parameters in the `[[DefineOwnProperty]]` internal method that is also
later called in `OrdinarySetWithOwnDescriptor`.

The `PlatformObject.[[DefineOwnProperty]]` has similair logic.

This change adds an optional parameter to the `[[DefineOwnProperty]]`
internal method so the results of the previous `[[GetOwnProperty]]`
internal method invocation can be re-used.
