Merge pull request #21258 from eplankin:fix_threshold_to_zero_ipp_bug
Fixed threshold(THRESH_TOZERO) at imgproc(IPP)

* Fixed #16085: imgproc(IPP): wrong result from threshold(THRESH_TOZERO)

* 1. Added test cases with float where all bits of mantissa equal 1, min and max float as inputs
2. Used nextafterf instead of cast to hex

* Used float value in test instead of hex and casts

* Changed input value in test

3da17c42a4 Use NaN-safe clip function.
This is to prevent more NaN to int conversions like in #21111.

542b3e8a64 Fix harmless signed integer overflow.
When computing:
t1 = (bayer[1] + bayer[bayer_step] + bayer[bayer_step+2] + bayer[bayer_step*2+1])*G2Y;
there is a T (unsigned short or char) multiplied by an int which can overflow.
Then again, it is stored to t1 which is unsigned so the overflow disappears.
Keeping all unsigned is safer.

Merge pull request #21112 from vrabaud:3.4_luv_overflow
* Fix integer overflow in cv::Luv2RGBinteger::process.

For LL=49, uu=205, vv=23, we end up with x=7373056 and y=458
which overflows y*x.

d4741eece1 Fix H clamping for very small negative values.
In case of very small negative h (e.g. -1e-40), with the current implementation,
you will go through the first condition and end up with h = 6.f, and will miss
the second condition.
