Aiden Park 9193a72864 Support booting to 64-bit kernel entry point (#550) ...

This will allow OsLoader payload to boot to 64-bit kernel entry point.
If CPU supports 64-bit mode and a kernel image has 64-bit entry point,
OsLoader will switch to 64-bit long mode and jump to the 64-bit entry
point. Otherwise, continue to boot to 32-bit entry point.
- Ported necessary code from EDK2 VitualMemory.c in MdeModulePkg
- Moved PagingLib from BootloaderCorePkg to BootloaderCommonPkg
- Removed unused FlushCacheLine
- TBD: 64-bit IDT

Next step is to support 64-bit Payload.
- 32-bit compatible mode
- 64-bit CryptoLib
- etc.
