[GSoC] New universal intrinsic backend for RVV

* Add new rvv backend (partially implemented).

* Modify the framework of Universal Intrinsic.

* Add CV_SIMD macro guards to current UI code.

* Use vlanes() instead of nlanes.

* Modify the UI test.

* Enable the new RVV (scalable) backend.

* Remove whitespace.

* Rename and some others modify.

* Update intrin.hpp but still not work on AVX/SSE

* Update conditional compilation macros.

* Use static variable for vlanes.

* Use max_nlanes for array defining.

6a4c3b61e6 Improve doc of calcHist overload that accepts vectors
It's not clear how ranges argument should be used in the overload of
calcHist that accepts std::vector. The main overload uses array of
arrays there, while std::vector overload uses a plain array. The code
interprets the vector as a flattened array and rebuilds array of arrays
from it. This is not obvious interpretation, so documentation has been
added to explain the expected usage.

Merge pull request #22149 from seanm:sprintf
Replaced sprintf with safer snprintf

* Straightforward replacement of sprintf with safer snprintf

* Trickier replacement of sprintf with safer snprintf

Some functions were changed to take another parameter: the size of the buffer, so that they can pass that size on to snprintf.

Merge pull request #21677 from chacha21:rectangle_intersection
* better accuracy of _rotatedRectangleIntersection

instead of just migrating to double-precision (which would work), some computations are scaled by a factor that depends on the length of the smallest vectors.
There is a better accuracy even with floats, so this is certainly better for very sensitive cases

* Update intersection.cpp

use L2SQR norm to tune the numeric scale

* Update intersection.cpp

adapt samePointEps with L2 norm

* Update intersection.cpp

move comment

* Update intersection.cpp

fix wrong numericalScalingFactor usage

* added tests

* fixed warnings returned by buildbot

* modifications suggested by reviewer

renaming numericalScaleFctor to normalizationScale
refactor some computations
more "const"

* modifications as suggested by reviewer

Merge pull request #21645 from chacha21:applyColorMap_8UC1_optimized
Optimize cv::applyColorMap() for simple case

* Optimize cv::applyColorMap() for simple case

PR for 21640
For regular cv::Mat CV_8UC1 src, applying the colormap is simpler than calling the cv::LUT() mechanism.

* add support for src as CV_8UC3

src as CV_8UC3 is handled with a BGR2GRAY conversion, the same optimized code being used afterwards

* code style

rely on cv::Mat.ptr() to index data

* Move new implementation to ColorMap::operator()

Changes as suggested by reviewer

* style

improvements suggsted by reviewer

* typo

* tune parallel work

* better usage of parallel_for_

use nstripes parameter of parallel_for_
assume _lut is continuous to bring faster pixel indexing
optimize src/dst access by contiguous rows of pixels
do not locally copy the LUT any more, it is no more relevant with the new optimizations
