Subject: [PATCH] feat(modem): Add factory method for simple creation of custom
 DCEs

This allows calling directly:
auto dce = dce_factory::Factory::create_unique_dce_from<SIM7600>(&dce_config, uart_dte, esp_netif);
instead of:
auto dce = create_SIM7600_dce(&dce_config, uart_dte, esp_netif);
Which is very useful when adding a custom module, so we won't need to
update factory layers and add the new device to enums, etc.
To add a new module, you just:
1) Define the module class NewModule: public GenericModule { };
2) Implement the specific commands:
command_result do_work_new_module(CommandableIf *t, params) {}
3) Connect 1) and 2)
command_result NewModule::do_work_new_module(params...)
{
    return dce_commands::do_work_new_module(dte.get(), params...);
}
