Update freetype to 2.12.1
ftdebug.c files are new, adapted the import script to copy the source file for Windows as well. Replaced the CMakeLists.txt content that was imported from the .pro file with the respective variables and logic from the freetype CMakeLists.txt file, which should make it easier to maintain this next time. Pick-to: 6.4 6.3 6.2 5.15 5.12 Fixes: QTBUG-105032 Change-Id: I1e846167b268df4b1b0a50dcec602def1a0bdcb4 Reviewed-by: Kai Koehne <kai.koehne@qt.io>
