feat(cmakev2): Create executable dummy source only if it does not exist

Browse Source 
idf_build_executable() creates a dummy source file to create the
executable target. Since this file is created unconditionally everytime
CMake configuration happens, a source file change is registered which
causes CMake to execute other targets even though no other source file
changed.
