chore (lfg-solo): clean up

Reduce script diff from master. LFG Solo was literally 90% core edit with a on off bool in a custom script folder. It made no sense. Time to revisit the idea of a cleanup
Remove Lgf_Solo.cpp from custom script folder
Remove announcement on login and in conf
Move  SoloLFG.Enable bool to the exsisting LFGPlayerScript::OnLogin.
