ArmVirtPkg; avoid DxeTpmMeasurementLib in shared .DSC

DxeTpmMeasurementLib should only be used on platforms that implement
measured boot, which we will do in a future patch, but only for
ArmVirtQemu, as the remaining ones are fundamentally incompatible,
given that they do not implement a PEI phase.

So use TpmMeasurementLibNull as the default resolution for all
ArmVirtPkg platforms, regardless of how they are built.

This mirrors commit 1ec05b81e59f ("OvmfPkg: use DxeTpmMeasurementLib
if and only if TPM2_ENABLE", 2019-07-04).
