Merge pull request #25564 from mshabunin:cleanup-imgproc-2
imgproc: C-API cleanup, drawContours refactor #25564

Changes:
* moved several macros from types_c.h to cvdef.h (assuming we will continue using them)
* removed some cases of C-API usage in _imgproc_ module (`CV_TERMCRIT_*` and `CV_CMP_*`)
* refactored `drawContours` to use C++ API instead of calling `cvDrawContours` + test for filled contours with holes (case with non-filled contours is simpler and is covered in some other tests)

#### Note:
There is one case where old drawContours behavior doesn't match the new one - when `contourIdx == -1` (means "draw all contours") and `maxLevel == 0` (means draw only selected contours, but not what is inside).

From the docs:
> **contourIdx**	Parameter indicating a contour to draw. If it is negative, all the contours are drawn.

> **maxLevel**	Maximal level for drawn contours. If it is 0, only the specified contour is drawn. If it is 1, the function draws the contour(s) and all the nested contours. If it is 2, the function draws the contours, all the nested contours, all the nested-to-nested contours, and so on. This parameter is only taken into account when there is hierarchy available.


Old behavior - only one first contour is drawn:

a
New behavior (also expected by the test) - all contours are drawn:

Merge pull request #25582 from fengyuentau:dnn/dump_pbtxt
Current net exporter `dump` and `dumpToFile` exports the network structure (and its params) to a .dot file which works with `graphviz`. This is hard to use and not friendly to new user. What's worse, the produced picture is not looking pretty.
dnn: better net exporter that works with netron #25582

This PR introduces new exporter `dumpToPbtxt` and uses this new exporter by default with environment variable `OPENCV_DNN_NETWORK_DUMP`. It mimics the string output of a onnx model but modified with dnn-specific changes, see below for an example.

![image](https://github.com/opencv/opencv/assets/17219438/0644bed1-da71-4019-8466-88390698e4df)

## Usage

Call `cv::dnn::Net::dumpToPbtxt`:

```cpp
TEST(DumpNet, dumpToPbtxt) {
    std::string path = "/path/to/model.onnx";
    auto net = readNet(path);

    Mat input(std::vector<int>{1, 3, 640, 480}, CV_32F);
    net.setInput(input);

    net.dumpToPbtxt("yunet.pbtxt");
}
```

Set `export OPENCV_DNN_NETWORK_DUMP=1`

```cpp
TEST(DumpNet, env) {
    std::string path = "/path/to/model.onnx";
    auto net = readNet(path);

    Mat input(std::vector<int>{1, 3, 640, 480}, CV_32F);
    net.setInput(input);

    net.forward();
}
```

---

Note:
- `pbtxt` is registered as one of the ONNX model suffix in netron. So you can see `module: ai.onnx` and such in the model.
- We can get the string output of an ONNX model with the following script

```python
import onnx
net = onnx.load("/path/to/model.onnx")
net_str = str(net)
file = open("/path/to/model.pbtxt", "w")
file.write(net_str)
file.close()
```

Merge pull request #25297 from CNOCycle:tflite/transpose
Support Transpose op in TFlite #25297

**Merge with extra**: https://github.com/opencv/opencv_extra/pull/1168

The purpose of this PR is to introduce support for the Transpose op in TFlite format and to add a shape comparison between the output tensors and the references. In some occasional cases, the shape of the output tensor is `[1,4,1,1]`, while the shape of the reference tensor is `[1,4]`. Consequently, the norm check incorrectly reports that the test has passed, as the residual is zero.

Below is a Python script for generating testing data. The generated data can be integrated into the repo `opencv_extra`.

```python
import numpy as np
import tensorflow as tf

PREFIX_TFL = '/path/to/opencv_extra/testdata/dnn/tflite/'

def generator(input_tensor, model, saved_name):

    # convert keras model to .tflite format
    converter = tf.lite.TFLiteConverter.from_keras_model(model)
    #converter.optimizations = [tf.lite.Optimize.DEFAULT]
    converter.optimizations = [None]
    tflite_model = converter.convert()
    with open(f'{PREFIX_TFL}/{saved_name}.tflite', 'wb') as f:
        f.write(tflite_model)

    # save the input tensor to .npy
    if input_tensor.ndim == 4:
        opencv_tensor = np.transpose(input_tensor, (0,3,1,2))
    else:
        opencv_tensor = input_tensor
    opencv_tensor = np.copy(opencv_tensor, order='C').astype(np.float32)
    np.save(f'{PREFIX_TFL}/{saved_name}_inp.npy', opencv_tensor)

    # generate output tenosr and save it to .npy
    mat_out = model(input_tensor).numpy()
    mat_out = np.copy(mat_out, order='C').astype(np.float32)
    if mat_out.ndim == 4:
        mat_out = np.transpose(mat_out, (0,3,1,2))
    interpreter = tf.lite.Interpreter(model_content=tflite_model)
    out_name = interpreter.get_output_details()[0]['name']
    np.save(f'{PREFIX_TFL}/{saved_name}_out_{out_name}.npy', mat_out)

def build_transpose():

    model_name = "keras_permute"
    mat_in = np.array([[[1,2,3], [4,5,6]]], dtype=np.float32)

    model = tf.keras.Sequential()
    model.add(tf.keras.Input(shape=(2,3)))
    model.add(tf.keras.layers.Permute((2,1)))
    model.summary()

    generator(mat_in, model, model_name)

if __name__ == '__main__':
    build_transpose()
```
