ArmVirtPkg: Kvmtool: Add RNG support using Arm TRNG interface 

Bugzilla: 3668 (https://bugzilla.tianocore.org/show_bug.cgi?id=3668)

The EFI_RNG_PROTOCOL published by RngDxe has been updated to
implement the EFI_RNG_ALGORITHM_RAW using the Arm TRNG interface
to provide access to entropy.

Therefore, enable EFI_RNG_PROTOCOL for the Kvmtool guest/virtual
firmware.
