feat: ":restart [cmd]" can run commands #35045

Browse Source 
Problem:
Not easy for a user to tell ":restart" to "run this command(s) after restarting".

Solution:
All ":restart" args following the optional +cmd arg are treated as a big cmdline that is passed as a "-c" CLI arg when restarting nvim.
