Merge pull request #20611 from VadimLevin:dev/vlevin/pure-python-modules
* feat: OpenCV extension with pure Python modules

* feat: cv2 is now a Python package instead of extension module

Python package cv2 now can handle both Python and C extension modules
properly without additional "subfolders" like "_extra_py_code".

* feat: can call native function from its reimplementation in Python

16b9514543 feat: update conversion logic for std::vector<T> in Python bindings
`PyObject*` to `std::vector<T>` conversion logic:
- If user passed Numpy Array
  - If array is planar and T is a primitive type (doesn't require
    constructor call) that matches with the element type of array, then
    copy element one by one with the respect of the step between array
    elements. If compiler is lucky (or brave enough) copy loop can be
    vectorized.
    For classes that require constructor calls this path is not
    possible, because we can't begin an object lifetime without hacks.
  - Otherwise fall-back to general case
- Otherwise - execute the general case:
  If PyObject* corresponds to Sequence protocol - iterate over the
  sequence elements and invoke the appropriate `pyopencv_to` function.

`std::vector<T>` to `PyObject*` conversion logic:
- If `std::vector<T>` is empty - return empty tuple.
- If `T` has a corresponding `Mat` `DataType` than return
  Numpy array instance of the matching `dtype` e.g.
  `std::vector<cv::Rect>` is returned as `np.ndarray` of shape `Nx4` and
  `dtype=int`.
  This branch helps to optimize further evaluations in user code.
- Otherwise - execute the general case:
  Construct a tuple of length N = `std::vector::size` and insert
  elements one by one.

Unnecessary functions were removed and code was rearranged to allow
compiler select the appropriate conversion function specialization.

6a4bfc0863 Stream default to Stream::Null() when no default in function prototype
this corrects bug #16592 where a Stream is created at
each GpuMat::load(arr,stream) call

a correct solution would have been to add a default to GpuMat::load
but due to circular dependence between Stream and GpuMat, this is not possible
add test_cuda_upload_download_stream to test_cuda.py

6c1a433c4c python: also catch general c++ exceptions
they might be thrown from third-party code (notably Ogre in the ovis
module).
While Linux is kind enough to print them, they cause instant termination
on Windows.
Arguably, they do not origin from OpenCV itself, but still this helps
understanding what went wrong when calling an OpenCV function.

Fix implicit conversion from array to scalar in python bindings

* Fix wrong conversion behavior for primitive types

  - Introduce ArgTypeInfo namedtuple instead of plain tuple.
    If strict conversion parameter for type is set to true, it is
    handled like object argument in PyArg_ParseTupleAndKeywords and
    converted to concrete type with the appropriate pyopencv_to function
    call.
  - Remove deadcode and unused variables.
  - Fix implicit conversion from numpy array with 1 element to scalar
  - Fix narrowing conversion to size_t type.

  - Fix implicit conversion from numpy array with 1 element to scalar
  - Fix narrowing conversion to size_t type.·
  - Enable tests with wrong conversion behavior
  - Restrict passing None as value
  - Restrict bool to integer/floating types conversion

* Add PyIntType support for Python 2

* Remove possible narrowing conversion of size_t

* Bindings conversion update

  - Remove unused macro
  - Add better conversion for types to numpy types descriptors
  - Add argument name to fail messages
  - NoneType treated as a valid argument. Better handling will be added
    as a standalone patch

* Add descriptor specialization for size_t

* Add check for signed to unsigned integer conversion safety

  - If signed integer is positive it can be safely converted
    to unsigned
  - Add check for plain python 2 objects
  - Add check for numpy scalars
  - Add simple type_traits implementation for better code style

* Resolve type "overflow" false negative in safe casting check

 - Move type_traits to separate header

* Add copyright message to type_traits.hpp

* Limit conversion scope for integral numpy types

  - Made canBeSafelyCasted specialized only for size_t, so
    type_traits header became unused and was removed.
  - Added clarification about descriptor pointer
