  1. Drive invalid in AXI VCs 

    When the 'valid' signal is low for an AXI (-Lite) channel, the signals of the channel should be driven with 'X'.
They should not keep their value from the last time the channel was valid.
This can hide errors in the DUT if the DUT samples values in the wrong clock cycle.

This change is largely inspired by the AXI-Stream VCs.
