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.

* fix broken code link

resolves  #15344

* Update stitcher.markdown

* update 3.4 link

* jas_stream: Add definition for L_tmpnam if missing

uClibc-ng for some reason does not provide a definition when some
deprecated APIs are disabled. Value taken from the musl libc.

* 3rdparty: move uClibc-ng workaround into config file
