NetworkPkg: Add WiFi Connection Manager to NetworkPkg

* V2

* Remove Arch dependency in Inf file
* Add a global guid for WiFi formset and set other guids to module levels
* Open supplicant and EapConfig by BY_DRIVER
* Remove token free function to avoid potential NULL reference
* Update WifiMgrUpdateConnectMessage() to only display message for Current Nic
* Fix the potential NULL reference in AIP call

* REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1492

Add WiFi Connection Manager in NetworkPkg to provide UI for users to scan
networks, connect or disconnect to networks.

This connection manager won't include the UNDI driver, supplicant driver,
or other device specific drivers and is therefor not a complete solution
stack for UEFI Wi-Fi, users can seek help for Wireless card vendors.
