Fix static build linking on windows

[tobil4sk]

There was a .lib file missing that's required for linking mbedtls, see: openfl/openfl#2603

This also fixes a change from #1529. The original PR mentions that debug causes the console subsystem, however, actually it's specifically the hxcpp-debugger that causes it. This meant that if running a debug build without the debugger, the following linker error would occur:

LIBCMT.lib(exe_winmain.obj) : error LNK2019: unresolved external symbol WinMain referenced in function "int __cdecl __scrt_common_main_seh(void)" (?__scrt_common_main_seh@@YAHXZ)
Main-debug.exe : fatal error LNK1120: 1 unresolved externals
