JavaScript: CV_OUT reference parameters are not handled properly

[alalek]

reproducer (test case): #21045 (commit)

JavaScript doesn't know anything about references. Parameters are passed by values.
So bindings should be updated.

Design options

Group outputs into:

• ✖ "object" (dictionary). Good for debugging (parameter names can be used). User code may not require changes if extra output parameter is added. Parameter rename would break user code.
• ✔ Array. Similar to Python (which returns tuple). Existed JS manual wrappers using this scheme

Note: ES6 destructuring assignment supports both arrays and objects.

Handling of arrays (OutputArray, InputOutputArray, CV_OUT Mat references):

• ✔ - include (Python behaves like that)
• ✖ - exclude arrays from result
