McuSupport: Update wizard entry point generation

Use app_target_default_main() macro and default entry points that come
with Qul instead providing own main.cpp templates.

Qt for MCUs has own default entry points implementations that may vary
for release to release. OS cmake variable is also removed in Qul 1.4.
