ArmVirtPkg: Add varpolicy shell command

Adds the varpolicy EFI shell command to all DSC files that
currently include other dynamic shell commands from ShellPkg.

This command allows variable policies to be dumped in the EFI
shell for convenient auditing and debug.

Use the command in the EFI shell as follows:

- `"varpolicy"` dumps platform variables
- `"varpolicy -?"` shows help text
- `"varpolicy -b"` pages output as expected
- `"varpolicy -s"` shows accurate variable statistic information
- `"varpolicy -p"` shows accurate UEFI variable policy information
- `"varpolicy-v -b"` dumps all information including variable data hex dump
