T-API: optimized cv::minMaxLoc, cv::norm with NORM_INF, cv::normalize with CV_MINMAX, CV_C

**Description:**
* optimized min/max calculation
* previously, `minMaxLoc` always found all min/max/minloc/maxloc, but now only if appropriate parameter isn't set to `NULL`
* used vector data types
* merged `abs`+`minMax` into `minMax` in norm with `NORM_INF`
