Add a new default autocommand to limit syntax highlighting synchronization in the command window. This refactors the nvim_terminal autocommand out of main() and into a new init_default_autocmds() function, which is now part of the startup process and can be further extended with more default autocommands down the road. ref #6289 #6399
