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
