OvmfPkg: Add RngLib based on TimerLib for Crypto

Updates the DSC's for Ovmf based platforms 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.
