[PATCH v7 4/5] ArmVirtPkg: Add RngLib based on TimerLib for CryptoPkg

["Matthew Carlson" <matthewfcarlson@gmail.com>]

From: Matthew Carlson <macarl@microsoft.com>

Updates the DSC for the ArmVirtPkg platform to add a RngLib that uses the
TimerLib. This is due to a later change that adds TimerLib as a dependency
for OpenSSL. The TimerLib based RngLib mimics the behavior of OpenSSL
previously and it is recommended to switch to a better source of
entropy than the system's performance counter.
