[CLEANUP] Remove redundant Object and ScriptedObject classes.

[Starexify]

Description

This PR removes the redundant Object and ScriptedObject classes from the base modding folder as there are no longer necessary in modding for initializing base classes.
Since ~0.7 polymod was updated to support initializing base classes without the need of using wrappers like ScriptedObject.

So instead of

class Test extends Object {
}

Mods can simply use these:

class Test {
}

honestly i see scenarios where the Object class and its scripted variant could be used, as the objects extending nothing in polymod tend to not work sometimes.
