* Convert ImgWarp from SSE SIMD to HAL - 2.8x faster on Power (VSX) and 15% speedup on x86

* Change compile flag from CV_SIMD128 to CV_SIMD128_64F for use of v_float64x2 type

* Changing WarpPerspectiveLine from class functions and dispatching to static functions.

* Re-add dynamic runtime and dispatch execution.

* RRestore SSE4_1 optimizations inside opt_SSE4_1 namespace

detected by UBSAN

* Fix IE FullyConnected layer

* Fix MyriadX

* Convert lkpyramid from SSE SIMD to HAL - 90% faster on Power (VSX).

* Replace stores with reduce_sum.  Rework to handle endianess correctly.

* Fix compiler warnings by casting values explicitly to shorts

* Switch to CV_SIMD128 compiler definition.  Unroll loop to 8 elements since we've already loaded the data.

Implementation of colormap "Turbo" (#15388)

* implemented turbo colormap

* add colormap image

* changed float value to avoid cast

* sorted flag check alphabetically

* Add debug build option to MacOs and iOS build scripts

* osx: allow selection of MACOSX_DEPLOYMENT_TARGET

* Add --debug_info flag to iOS and macOS builds for building with debug info

The deprecated flag ENABLE_VSX should not be used to enable this
feature. Instead, use the baseline cpu feature set to determine.
