Implement constructor invocation APIs in LSPosedContext (#533) 

Unlike the existing `newInstance` variants which allocate and return a new object, these new APIs execute constructor logic on an existing, pre-allocated instance (`thisObject`). This separation of allocation and initialization allows for invoking original or super constructors within hook callbacks where the object reference is already established.

The implementation leverages the existing JNI `HookBridge` methods, as `invokeOriginalMethod` and `invokeSpecialMethod` already support void-return signatures required for constructor execution.
