CMakeLists.txt: add a option (BUILD_SMALL_DEBUG_FILES, default off) to create smaller binaries in debug mode.

It forces link option -g1 instead og -g3 which allows basic debug.

This is especially useful on Mingw because binaries in debug build are very large:
_pcbnew.kiface: 1.25 Gb, small file option: 65Mb
