Cleanup of Windows tasks in zabbix_agent

[meis4h]

SUMMARY

This change cleans up the Windows tasks of the zabbix_agent role and fixes several issues.
No existing functionality is changed or removed (hopefully).

• Add windows specific version of zabbix_agent_win_controlsocket and zabbix_agent_win_pluginsocket to avoid setting unix default values
• Add zabbix_win_config_remove variable to optionally prevent deletion of extra configuration inside of zabbix_agent2.d on updates
• Add loop labels to reduce output clutter
• Fix detection of currently installed version (solves the same issue as Windows agent installation. #1139 but only noticed the PR while already submitting)
• Fix usage of zabbix_win_install_dir_ variables throughout all tasks and add temporary "setup" direcory to avoid issues when using different paths
• Clean up some never used variables and combine some redundant set_facts tasks
• Avoid unneeded agent restarts which caused errors on some hosts
